................................................................................
this points to the first byte of an array of \fIlength\fR bytes
containing a string to append to the \fB\-errorinfo\fR return option.
This byte array may contain embedded null bytes
unless \fIlength\fR is negative.
.AP Tcl_Obj *objPtr in
A message to be appended to the \fB\-errorinfo\fR return option
in the form of a Tcl_Obj value.
.AP size_t length in
The number of bytes to copy from \fImessage\fR when
appending to the \fB\-errorinfo\fR return option.
If TCL_AUTO_LENGTH, all bytes up to the first null byte are used.
.AP Tcl_Obj *errorObjPtr in
The \fB\-errorcode\fR return option will be set to this value.
.AP char *element in
String to record as one element of the \fB\-errorcode\fR return option.
Last \fIelement\fR argument must be NULL.
.AP va_list argList in
An argument list which must have been initialized using
................................................................................
the \fB\-errorcode\fR return option to \fBNONE\fR.
.PP
The procedure \fBTcl_SetErrorCode\fR is also used to set the
\fB\-errorcode\fR return option. However, it takes one or more strings to
record instead of a value. Otherwise, it is similar to
\fBTcl_SetObjErrorCode\fR in behavior.
.PP



The procedure \fBTcl_GetErrorLine\fR is used to read the integer value
of the \fB\-errorline\fR return option without the overhead of a full
call to \fBTcl_GetReturnOptions\fR.  Likewise, \fBTcl_SetErrorLine\fR
sets the \fB\-errorline\fR return option value.
.PP
\fBTcl_PosixError\fR
sets the \fB\-errorcode\fR variable after an error in a POSIX kernel call.

this points to the first byte of an array of \fIlength\fR bytes
containing a string to append to the \fB\-errorinfo\fR return option.
This byte array may contain embedded null bytes
unless \fIlength\fR is negative.
.AP Tcl_Obj *objPtr in
A message to be appended to the \fB\-errorinfo\fR return option
in the form of a Tcl_Obj value.
.AP int length in
The number of bytes to copy from \fImessage\fR when
appending to the \fB\-errorinfo\fR return option.
If negative, all bytes up to the first null byte are used.
.AP Tcl_Obj *errorObjPtr in
The \fB\-errorcode\fR return option will be set to this value.
.AP char *element in
String to record as one element of the \fB\-errorcode\fR return option.
Last \fIelement\fR argument must be NULL.
.AP va_list argList in
An argument list which must have been initialized using
................................................................................
the \fB\-errorcode\fR return option to \fBNONE\fR.
.PP
The procedure \fBTcl_SetErrorCode\fR is also used to set the
\fB\-errorcode\fR return option. However, it takes one or more strings to
record instead of a value. Otherwise, it is similar to
\fBTcl_SetObjErrorCode\fR in behavior.
.PP
\fBTcl_SetErrorCodeVA\fR is the same as \fBTcl_SetErrorCode\fR except that
instead of taking a variable number of arguments it takes an argument list.
.PP
The procedure \fBTcl_GetErrorLine\fR is used to read the integer value
of the \fB\-errorline\fR return option without the overhead of a full
call to \fBTcl_GetReturnOptions\fR.  Likewise, \fBTcl_SetErrorLine\fR
sets the \fB\-errorline\fR return option value.
.PP
\fBTcl_PosixError\fR
sets the \fB\-errorcode\fR variable after an error in a POSIX kernel call.

as macros, redefined to be special debugging versions of these procedures.

calling Tcl are compiled with \fBTCL_MEM_DEBUG\fR defined, however,


these macros are redefined to be special debugging versions

This is a utility procedure provided for backwards compatibility with
non-internationalized Tcl extensions.  It parses a backslash sequence and
returns the low byte of the Unicode character corresponding to the sequence.
\fBTcl_Backslash\fR modifies \fI*countPtr\fR to contain the number of

.PP
Every object has its own command and namespace associated with it. The command
may be retrieved using the \fBTcl_GetObjectCommand\fR function, the name of
the object (and hence the name of the command) with \fBTcl_GetObjectName\fR,
and the namespace may be retrieved using the \fBTcl_GetObjectNamespace\fR
function. Note that the Tcl_Obj reference returned by \fBTcl_GetObjectName\fR
is a shared reference.


.PP
Instances of classes are created using \fBTcl_NewObjectInstance\fR, which
creates an object from any class (and which is internally called by both
the \fBcreate\fR and \fBnew\fR methods of the \fBoo::class\fR class). It takes
parameters that optionally give the name of the object and namespace to
create, and which describe the arguments to pass to the class's constructor
(if any). The result of the function will be either a reference to the newly
created object, or NULL if the creation failed (when an error message will be
left in the interpreter result). In addition, objects may be copied by using
\fBTcl_CopyObjectInstance\fR which creates a copy of an object without running
any constructors.

Every object has its own command and namespace associated with it. The command
may be retrieved using the \fBTcl_GetObjectCommand\fR function, the name of
the object (and hence the name of the command) with \fBTcl_GetObjectName\fR,
and the namespace may be retrieved using the \fBTcl_GetObjectNamespace\fR

is a shared reference. You can also get whether the object has been marked for
deletion with \fBTcl_ObjectDeleted\fR (it returns true if deletion of the
object has begun); this can be useful during the processing of methods.
.PP
Instances of classes are created using \fBTcl_NewObjectInstance\fR, which
creates an object from any class (and which is internally called by both
the \fBcreate\fR and \fBnew\fR methods of the \fBoo::class\fR class). It takes

left in the interpreter result). In addition, objects may be copied by using
\fBTcl_CopyObjectInstance\fR which creates a copy of an object without running
any constructors.
.PP
Note that the lifetime management of objects is handled internally within
TclOO, and does not use \fBTcl_Preserve\fR. \fIIt is not safe to put a
Tcl_Object handle in a C structure with a lifespan different to the object;\fR
you should use the object's command name (as retrieved with
\fBTcl_GetObjectName\fR) instead. It is safe to use a Tcl_Object handle for
the lifespan of a call of a method on that object; handles do not become
invalid while there is an outstanding call on their object (even if the only
operation guaranteed to be safe on them is \fBTcl_ObjectDeleted\fR; the other
operations are only guaranteed to work on non-deleted objects).

The name of this channel, such as \fBfile3\fR; must not be in use
by any other channel. Can be NULL, in which case the channel is
created without a name. If the created channel is assigned to one
of the standard channels (\fBstdin\fR, \fBstdout\fR or \fBstderr\fR),
the assigned channel name will be the name of the standard channel.
.AP void *instanceData in
Arbitrary one-word value to be associated with this channel.  This
value is passed to procedures in \fItypePtr\fR when they are invoked.
.AP int mask in
OR-ed combination of \fBTCL_READABLE\fR and \fBTCL_WRITABLE\fR to indicate
whether a channel is readable and writable.
.AP Tcl_Channel channel in
The channel to operate on.

.SH "NOTICE OF EVENTUAL DEPRECATION"
.PP
The \fBTcl_CreateMathFunc\fR and \fBTcl_GetMathFuncInfo\fR functions
are rendered somewhat obsolete by the ability to create functions for
expressions by placing commands in the \fBtcl::mathfunc\fR namespace,
as described in the \fBmathfunc\fR manual page; the API described on
this page is not expected to be maintained indefinitely.

.SH ARGUMENTS
.AS Tcl_ValueType *clientDataPtr out
.AP Tcl_Interp *interp in
Interpreter in which new function will be defined.
.AP "const char" *name in
Name for new function.
.AP int numArgs in
Number of arguments to new function;  also gives size of \fIargTypes\fR array.
.AP Tcl_ValueType *argTypes in
Points to an array giving the permissible types for each argument to

.AP Tcl_MathProc *proc in
Procedure that implements the function.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR when it is invoked.
.AP int *numArgsPtr out
Points to a variable that will be set to contain the number of
arguments to the function.
.AP Tcl_ValueType **argTypesPtr out
Points to a variable that will be set to contain a pointer to an array
giving the permissible types for each argument to the function which
will need to be freed up using \fITcl_Free\fR.
.AP Tcl_MathProc **procPtr out
Points to a variable that will be set to contain a pointer to the
implementation code for the function (or NULL if the function is
implemented directly in bytecode).
.AP ClientData *clientDataPtr out
Points to a variable that will be set to contain the clientData
argument passed to \fITcl_CreateMathFunc\fR when the function was
created if the function is not implemented directly in bytecode.
.AP "const char" *pattern in
Pattern to match against function names so as to filter them (by
passing to \fITcl_StringMatch\fR), or NULL to not apply any filter.
.BE
.SH DESCRIPTION
.PP
Tcl allows a number of mathematical functions to be used in
expressions, such as \fBsin\fR, \fBcos\fR, and \fBhypot\fR.
These functions are represented by commands in the namespace,
\fBtcl::mathfunc\fR.  The \fBTcl_CreateMathFunc\fR function is
an obsolete way for applications to add additional functions
to those already provided by Tcl or to replace existing functions.
It should not be used by new applications, which should create
math functions using \fBTcl_CreateObjCommand\fR to create a command
in the \fBtcl::mathfunc\fR namespace.
.PP
In the \fBTcl_CreateMathFunc\fR interface,
\fIName\fR is the name of the function as it will appear in expressions.
If \fIname\fR does not already exist in the \fB::tcl::mathfunc\fR
namespace, then a new command is created in that namespace.
If \fIname\fR does exist, then the existing function is replaced.
\fINumArgs\fR and \fIargTypes\fR describe the arguments to the function.
Each entry in the \fIargTypes\fR array must be
one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR, \fBTCL_WIDE_INT\fR,
or \fBTCL_EITHER\fR to indicate whether the corresponding argument must be an
integer, a double-precision floating value, a wide (64-bit) integer,
or any, respectively.
.PP
Whenever the function is invoked in an expression Tcl will invoke
\fIproc\fR.  \fIProc\fR should have arguments and result that match
the type \fBTcl_MathProc\fR:
.PP
.CS
typedef int \fBTcl_MathProc\fR(
        ClientData \fIclientData\fR,
        Tcl_Interp *\fIinterp\fR,
        Tcl_Value *\fIargs\fR,
        Tcl_Value *\fIresultPtr\fR);
.CE
.PP
When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
arguments will be the same as those passed to \fBTcl_CreateMathFunc\fR.
\fIArgs\fR will point to an array of \fInumArgs\fR Tcl_Value structures,
which describe the actual arguments to the function:
.PP
.CS
typedef struct Tcl_Value {
    Tcl_ValueType \fItype\fR;
    long \fIintValue\fR;
    double \fIdoubleValue\fR;
    Tcl_WideInt \fIwideValue\fR;
} \fBTcl_Value\fR;
.CE
.PP
The \fItype\fR field indicates the type of the argument and is
one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR.
It will match the \fIargTypes\fR value specified for the function unless
the \fIargTypes\fR value was \fBTCL_EITHER\fR. Tcl converts
the argument supplied in the expression to the type requested in
\fIargTypes\fR, if that is necessary.
Depending on the value of the \fItype\fR field, the \fIintValue\fR,
\fIdoubleValue\fR or \fIwideValue\fR
field will contain the actual value of the argument.
.PP
\fIProc\fR should compute its result and store it either as an integer
in \fIresultPtr->intValue\fR or as a floating value in
\fIresultPtr->doubleValue\fR.
It should set also \fIresultPtr->type\fR to one of
\fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR
to indicate which value was set.
Under normal circumstances \fIproc\fR should return \fBTCL_OK\fR.
If an error occurs while executing the function, \fIproc\fR should
return \fBTCL_ERROR\fR and leave an error message in the interpreter's result.
.PP
\fBTcl_GetMathFuncInfo\fR retrieves the values associated with
function \fIname\fR that were passed to a preceding
\fBTcl_CreateMathFunc\fR call.  Normally, the return code is
\fBTCL_OK\fR but if the named function does not exist, \fBTCL_ERROR\fR
is returned and an error message is placed in the interpreter's
result.
.PP
If an error did not occur, the array reference placed in the variable
pointed to by \fIargTypesPtr\fR is newly allocated, and should be
released by passing it to \fBTcl_Free\fR.  Some functions (the
standard set implemented in the core, and those defined by placing
commands in the \fBtcl::mathfunc\fR namespace) do not have
argument type information; attempting to retrieve values for
them causes a NULL to be stored in the variable pointed to by
\fIprocPtr\fR and the variable pointed to by \fIclientDataPtr\fR
will not be modified.  The variable pointed to by \fInumArgsPointer\fR
will contain -1, and no argument types will be stored in the variable
pointed to by \fIargTypesPointer\fR.
.PP
\fBTcl_ListMathFuncs\fR returns a Tcl value containing a list of all
the math functions defined in the interpreter whose name matches
\fIpattern\fR.  The returned value has a reference count of zero.

\fIClientData\fR typically points to an application-specific data

\fIlevel\fR parameter gives the nesting level of the command (1 for
top-level commands passed to \fBTcl_Eval\fR by the application, 2 for
the next-level commands passed to \fBTcl_Eval\fR as part of parsing or

.PP
The procedures described here provide a graceful mechanism to end the
execution of a \fBTcl\fR application. Exit handlers are invoked to cleanup the
................................................................................
Note that if other code invokes \fBexit\fR system procedure directly, or
otherwise causes the application to terminate without calling
\fBTcl_Exit\fR, the exit handlers will not be run.
\fBTcl_Exit\fR internally invokes the \fBexit\fR system call, thus it never
returns control to its caller.
If an application exit handler has been installed (see
\fBTcl_SetExitProc\fR), that handler is invoked with an argument
consisting of the exit status (cast to void *); the application
exit handler should not return control to Tcl.
.PP
\fBTcl_Finalize\fR is similar to \fBTcl_Exit\fR except that it does not
exit from the current process.
It is useful for cleaning up when a process is finished using \fBTcl\fR but
wishes to continue executing, and when \fBTcl\fR is used in a dynamically
loaded extension that is about to be unloaded.
................................................................................
by \fBTcl_FinalizeThread\fR and \fBTcl_ExitThread\fR.
This provides a hook for cleanup operations such as flushing buffers
and freeing global memory.
\fIProc\fR should match the type \fBTcl_ExitProc\fR:
.PP
.CS
typedef void \fBTcl_ExitProc\fR(
        void *\fIclientData\fR);
.CE
.PP
The \fIclientData\fR parameter to \fIproc\fR is a
copy of the \fIclientData\fR argument given to
\fBTcl_CreateExitHandler\fR or \fBTcl_CreateThreadExitHandler\fR when
the callback
was created.  Typically, \fIclientData\fR points to a data
................................................................................
\fBTcl_SetExitProc\fR installs an application exit handler, returning
the previously-installed application exit handler or NULL if no
application handler was installed.  If an application exit handler is
installed, that exit handler takes over complete responsibility for

.SH DESCRIPTION
.PP
The procedures described here provide a graceful mechanism to end the
execution of a \fBTcl\fR application. Exit handlers are invoked to cleanup the
................................................................................
Note that if other code invokes \fBexit\fR system procedure directly, or
otherwise causes the application to terminate without calling
\fBTcl_Exit\fR, the exit handlers will not be run.
\fBTcl_Exit\fR internally invokes the \fBexit\fR system call, thus it never
returns control to its caller.
If an application exit handler has been installed (see
\fBTcl_SetExitProc\fR), that handler is invoked with an argument
consisting of the exit status (cast to ClientData); the application
exit handler should not return control to Tcl.
.PP
\fBTcl_Finalize\fR is similar to \fBTcl_Exit\fR except that it does not
exit from the current process.
It is useful for cleaning up when a process is finished using \fBTcl\fR but
wishes to continue executing, and when \fBTcl\fR is used in a dynamically
loaded extension that is about to be unloaded.
................................................................................
by \fBTcl_FinalizeThread\fR and \fBTcl_ExitThread\fR.
This provides a hook for cleanup operations such as flushing buffers
and freeing global memory.
\fIProc\fR should match the type \fBTcl_ExitProc\fR:
.PP
.CS
typedef void \fBTcl_ExitProc\fR(
        ClientData \fIclientData\fR);
.CE
.PP
The \fIclientData\fR parameter to \fIproc\fR is a
copy of the \fIclientData\fR argument given to
\fBTcl_CreateExitHandler\fR or \fBTcl_CreateThreadExitHandler\fR when
the callback
was created.  Typically, \fIclientData\fR points to a data
................................................................................
\fBTcl_SetExitProc\fR installs an application exit handler, returning
the previously-installed application exit handler or NULL if no
application handler was installed.  If an application exit handler is
installed, that exit handler takes over complete responsibility for
finalization of Tcl's subsystems via \fBTcl_Finalize\fR at an
appropriate time.  The argument passed to \fIproc\fR when it is
invoked will be the exit status code (as passed to \fBTcl_Exit\fR)
cast to a ClientData value.
.PP
\fBTcl_SetExitProc\fR can not be used in stub-enabled extensions. Its symbol
entry in the stub table is deprecated and it will be removed in Tcl 9.0.

\fBTcl_FSGetTranslatedStringPath\fR does the same as

.nf
\fB#include <tcl.h>\fR
.sp
void
\fBTcl_InitSubsystems\fR(\fIvoid\fR)
.SH DESCRIPTION
.PP
The \fBTcl_InitSubsystems\fR procedure initializes the Tcl
library. This procedure is typically invoked as the very
first thing in the application's main program.
.PP
\fBTcl_InitSubsystems\fR is very similar in use to
\fBTcl_FindExecutable\fR. It can be used when Tcl is
used as utility library, no other encodings than utf8,
iso8859-1 or unicode are used, and no interest exists in the
value of \fBinfo nameofexecutable\fR. The system encoding will not
be extracted from the environment, but falls back to iso8859-1.

the pointer as described below is no longer supported.  The supported
public routines \fBTcl_SetResult\fR, \fBTcl_GetResult\fR,

The \fIresult\fR and \fIfreeProc\fR fields are used to return
results or error messages from commands.
This information is returned by command procedures back to \fBTcl_Eval\fR,
and by \fBTcl_Eval\fR back to its callers.
The \fIresult\fR field points to the string that represents the
result or error message, and the \fIfreeProc\fR field tells how
to dispose of the storage for the string when it is not needed anymore.

\fIclientData\fR requires no deletion.
.BE
.SH DESCRIPTION
................................................................................
To add a handler callback to be invoked when a limit is exceeded, call
\fBTcl_LimitAddHandler\fR.  The \fIhandlerProc\fR argument describes
the function that will actually be called; it should have the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerProc\fR(
        void *\fIclientData\fR,
        Tcl_Interp *\fIinterp\fR);
.CE
.PP
The \fIclientData\fR argument to the handler will be whatever is
passed to the \fIclientData\fR argument to \fBTcl_LimitAddHandler\fR,
and the \fIinterp\fR is the interpreter that had its limit exceeded.
.PP
................................................................................
\fBTCL_STATIC\fR or NULL if no deletion action is necessary, or
\fBTCL_DYNAMIC\fR if all that is necessary is to free the structure with
\fBTcl_Free\fR.  Otherwise, it should refer to a function with the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerDeleteProc\fR(
        void *\fIclientData\fR);
.CE
.PP
A limit handler may be deleted using \fBTcl_LimitRemoveHandler\fR; the
handler removed will be the first one found (out of the handlers added
with \fBTcl_LimitAddHandler\fR) with exactly matching \fItype\fR,
\fIhandlerProc\fR and \fIclientData\fR arguments.  This function
always invokes the \fIdeleteProc\fR on the \fIclientData\fR (unless
the \fIdeleteProc\fR was NULL or \fBTCL_STATIC\fR).

the handler returns.  Many handlers may be attached to the same
interpreter limit; their order of execution is not defined, and they
must be identified by \fIhandlerProc\fR and \fIclientData\fR when they
are deleted.
.AP ClientData clientData in
Arbitrary pointer-sized word used to pass some context to the
\fIhandlerProc\fR function.
.AP Tcl_LimitHandlerDeleteProc *deleteProc in
Function to call whenever a handler is deleted.  May be NULL if the
\fIclientData\fR requires no deletion.
.BE
.SH DESCRIPTION
................................................................................
To add a handler callback to be invoked when a limit is exceeded, call
\fBTcl_LimitAddHandler\fR.  The \fIhandlerProc\fR argument describes
the function that will actually be called; it should have the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerProc\fR(
        ClientData \fIclientData\fR,
        Tcl_Interp *\fIinterp\fR);
.CE
.PP
The \fIclientData\fR argument to the handler will be whatever is
passed to the \fIclientData\fR argument to \fBTcl_LimitAddHandler\fR,
and the \fIinterp\fR is the interpreter that had its limit exceeded.
.PP
................................................................................
\fBTCL_STATIC\fR or NULL if no deletion action is necessary, or
\fBTCL_DYNAMIC\fR if all that is necessary is to free the structure with
\fBTcl_Free\fR.  Otherwise, it should refer to a function with the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerDeleteProc\fR(
        ClientData \fIclientData\fR);
.CE
.PP
A limit handler may be deleted using \fBTcl_LimitRemoveHandler\fR; the
handler removed will be the first one found (out of the handlers added
with \fBTcl_LimitAddHandler\fR) with exactly matching \fItype\fR,
\fIhandlerProc\fR and \fIclientData\fR arguments.  This function
always invokes the \fIdeleteProc\fR on the \fIclientData\fR (unless
the \fIdeleteProc\fR was NULL or \fBTCL_STATIC\fR).
.SH KEYWORDS
interpreter, resource, limit, commands, time, callback

\fBTCL_LINK_STRING\fR
.
The C variable is of type \fBchar *\fR.
If its value is not NULL then it must be a pointer to a string
allocated with \fBTcl_Alloc\fR.
Whenever the Tcl variable is modified the current C string will be
freed and new memory will be allocated to hold a copy of the variable's
new value.
If the C variable contains a NULL pointer then the Tcl variable
will read as
.QW NULL .
This is only supported by \fBTcl_LinkVar\fR.

................................................................................
source must work with the notifier to detect events at the right
times, record them on the event queue, and eventually notify
higher-level software that they have occurred.  The procedures
\fBTcl_CreateEventSource\fR, \fBTcl_DeleteEventSource\fR,
and \fBTcl_SetMaxBlockTime\fR, \fBTcl_QueueEvent\fR, and
\fBTcl_DeleteEvents\fR are used primarily by event sources.
.IP [2]
The event queue: for non-threaded applications,
there is a single queue for the whole application,
containing events that have been detected but not yet serviced.  Event
sources place events onto the queue so that they may be processed in
order at appropriate times during the event loop. The event queue
guarantees a fair discipline of event handling, so that no event
source can starve the others.  It also allows events to be saved for
servicing at a future time.  Threaded applications work in a
similar manner, except that there is a separate event queue for
each thread containing a Tcl interpreter.
\fBTcl_QueueEvent\fR is used (primarily
by event sources) to add events to the event queue and
\fBTcl_DeleteEvents\fR is used to remove events from the queue without
processing them.  In a threaded application, \fBTcl_QueueEvent\fR adds
an event to the current thread's queue, and \fBTcl_ThreadQueueEvent\fR
adds an event to a queue in a specific thread.
.IP [3]
The event loop: in order to detect and process events, the application
enters a loop that waits for events to occur, places them on the event
queue, and then processes them.  Most applications will do this by
calling the procedure \fBTcl_DoOneEvent\fR, which is described in a
separate manual entry.
.PP
................................................................................
The procedure \fBTcl_CreateEventSource\fR creates a new event source.
Its arguments specify the setup procedure and check procedure for
the event source.
\fISetupProc\fR should match the following prototype:
.PP
.CS
typedef void \fBTcl_EventSetupProc\fR(
        void *\fIclientData\fR,
        int \fIflags\fR);
.CE
.PP
The \fIclientData\fR argument will be the same as the \fIclientData\fR
argument to \fBTcl_CreateEventSource\fR;  it is typically used to
point to private information managed by the event source.
The \fIflags\fR argument will be the same as the \fIflags\fR
................................................................................
The second procedure provided by each event source is its check
procedure, indicated by the \fIcheckProc\fR argument to
\fBTcl_CreateEventSource\fR.  \fICheckProc\fR must match the
following prototype:
.PP
.CS
typedef void \fBTcl_EventCheckProc\fR(
        void *\fIclientData\fR,
        int \fIflags\fR);
.CE
.PP
The arguments to this procedure are the same as those for \fIsetupProc\fR.
\fBCheckProc\fR is invoked by \fBTcl_DoOneEvent\fR after it has waited
for events.  Presumably at least one event source is now prepared to
queue an event.  \fBTcl_DoOneEvent\fR calls each of the event sources
................................................................................
Another example of deferring events happens in Tk if
\fBTk_RestrictEvents\fR has been invoked to defer certain kinds
of window events.
.PP
When \fIproc\fR returns 1, \fBTcl_ServiceEvent\fR will remove the
event from the event queue and free its storage.
Note that the storage for an event must be allocated by
the event source (using \fBTcl_Alloc\fR)
before calling \fBTcl_QueueEvent\fR, but it
will be freed by \fBTcl_ServiceEvent\fR, not by the event source.
.PP
Threaded applications work in a
similar manner, except that there is a separate event queue for
each thread containing a Tcl interpreter.
Calling \fBTcl_QueueEvent\fR in a multithreaded application adds
an event to the current thread's queue.
To add an event to another thread's queue, use \fBTcl_ThreadQueueEvent\fR.
\fBTcl_ThreadQueueEvent\fR accepts as an argument a Tcl_ThreadId argument,
which uniquely identifies a thread in a Tcl application.  To obtain the
Tcl_ThreadId for the current thread, use the \fBTcl_GetCurrentThread\fR
procedure.  (A thread would then need to pass this identifier to other
threads for those threads to be able to add events to its queue.)
After adding an event to another thread's queue, you then typically

for each event in the queue, deleting those for with the procedure
returns 1.  Events for which the procedure returns 0 are left in the
queue.  \fIProc\fR should match the following prototype:
.PP
.CS
typedef int \fBTcl_EventDeleteProc\fR(
        Tcl_Event *\fIevPtr\fR,
        void *\fIclientData\fR);
.CE
.PP
The \fIclientData\fR argument will be the same as the \fIclientData\fR
argument to \fBTcl_DeleteEvents\fR; it is typically used to point to
private information managed by the event source.  The \fIevPtr\fR will
point to the next event in the queue.
.PP
................................................................................
elapsed).  Finally, a return value of \-1 means that the event loop is
no longer operational and the application should probably unwind and
terminate.  Under Windows this happens when a WM_QUIT message is received;
under Unix it happens when \fBTcl_WaitForEvent\fR would have waited
forever because there were no active event sources and the timeout was
infinite.
.PP
\fBTcl_AlertNotifier\fR is used in multithreaded applications to allow
any thread to
.QW "wake up"
the notifier to alert it to new events on its
queue.  \fBTcl_AlertNotifier\fR requires as an argument the notifier
handle returned by \fBTcl_InitNotifier\fR.
.PP
If the notifier will be used with an external event loop, then it must
also support the \fBTcl_SetTimer\fR interface.  \fBTcl_SetTimer\fR is

We require the string representation's byte array
to have a null after the last byte, at offset \fIlength\fR,
and to have no null bytes before that; this allows string representations
to be treated as conventional null character-terminated C strings.
These restrictions are easily met by using Tcl's internal UTF encoding
for the string representation, same as one would do for other
Tcl routines accepting string values as arguments.
Storage for the byte array must be allocated in the heap by \fBTcl_Alloc\fR.
Note that \fIupdateStringProc\fRs must allocate
enough storage for the string's bytes and the terminating null byte.
.PP
The \fIupdateStringProc\fR for Tcl's built-in double type, for example,
calls Tcl_PrintDouble to write to a buffer of size TCL_DOUBLE_SPACE,
then allocates and copies the string representation to just enough
space to hold it.  A pointer to the allocated space is stored in
the \fIbytes\fR member.

Otherwise, the data will replace the existing contents of the value.
.AP char *readBuf out
A buffer in which to store the bytes read from the channel.
.AP size_t bytesToRead in
The number of bytes to read from the channel.  The buffer \fIreadBuf\fR must
be large enough to hold this many bytes.
.AP Tcl_Obj *lineObjPtr in/out
A pointer to a Tcl value in which to store the line read from the
channel.  The line read will be appended to the current value of the

.AP Tcl_DString *lineRead in/out
A pointer to a Tcl dynamic string in which to store the line read from the

appended to any data already in the dynamic string.
.AP "const char" *input in
The input to add to a channel buffer.
.AP size_t inputLen in
Length of the input
.AP int addAtEnd in
Flag indicating whether the input should be added to the end or

.AP Tcl_Obj *writeObjPtr in
A pointer to a Tcl value whose contents will be output to the channel.
.AP "const char" *charBuf in
A buffer containing the characters to output to the channel.
.AP "const char" *byteBuf in
A buffer containing the bytes to output to the channel.
.AP size_t bytesToWrite in
The number of bytes to consume from \fIcharBuf\fR or \fIbyteBuf\fR and
output to the channel.
.AP Tcl_WideInt offset in
How far to move the access point in the channel at which the next input or
output operation will be applied, measured in bytes from the position

error for argc and argv to override stdio channels for which
\fBTCL_STDIN\fR, \fBTCL_STDOUT\fR, and \fBTCL_STDERR\fR have been set.
.PP
If an error occurs while opening the channel, \fBTcl_OpenCommandChannel\fR
returns NULL and records a POSIX error code that can be retrieved with
\fBTcl_GetErrno\fR.
In addition, \fBTcl_OpenCommandChannel\fR leaves an error message in
the interpreter's result if \fIinterp\fR is not NULL.
.PP
The newly created channel is not registered in the supplied interpreter; to
register it, use \fBTcl_RegisterChannel\fR, described below.
If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
previously closed, the act of creating the new channel also assigns it as a
replacement for the standard channel.

\fBTcl_EvalTokens\fR differs from \fBTcl_EvalTokensStandard\fR only in
the return convention used: it returns the result in a new Tcl_Obj.
The reference count of the value returned as result has been
incremented, so the caller must
invoke \fBTcl_DecrRefCount\fR when it is finished with the value.
If an error or other exception occurs while evaluating the tokens
(such as a reference to a non-existent variable) then the return value
is NULL and an error message is left in \fIinterp\fR's result. The use
of \fBTcl_EvalTokens\fR is deprecated.

.SH ARGUMENTS
.AS "const Tcl_UniChar" *appendObjPtr in/out
.AP "const char" *bytes in
Points to the first byte of an array of UTF-8-encoded bytes
used to set or append to a string value.
This byte array may contain embedded null characters
unless \fInumChars\fR is TCL_AUTO_LENGTH.  (Applications needing null bytes
should represent them as the two-byte sequence \fI\e700\e600\fR, use
\fBTcl_ExternalToUtf\fR to convert, or \fBTcl_NewByteArrayObj\fR if
the string is a collection of uninterpreted bytes.)
.AP size_t length in
The number of bytes to copy from \fIbytes\fR when
initializing, setting, or appending to a string value.
If TCL_AUTO_LENGTH, all bytes up to the first null are used.
.AP "const Tcl_UniChar" *unicode in
Points to the first byte of an array of Unicode characters
used to set or append to a string value.
This byte array may contain embedded null characters
unless \fInumChars\fR is negative.
.AP size_t numChars in
The number of Unicode characters to copy from \fIunicode\fR when
initializing, setting, or appending to a string value.
If TCL_AUTO_LENGTH, all characters up to the first null character are used.
.AP size_t index in
The index of the Unicode character to return.
.AP size_t first in
The index of the first Unicode character in the Unicode range to be
returned as a new value.
.AP size_t last in
The index of the last Unicode character in the Unicode range to be
returned as a new value.
.AP Tcl_Obj *objPtr in/out
Points to a value to manipulate.
.AP Tcl_Obj *appendObjPtr in
The value to append to \fIobjPtr\fR in \fBTcl_AppendObjToObj\fR.
.AP int *lengthPtr out
................................................................................
If non-NULL, the location where \fBTcl_GetStringFromObj\fR will store
the length of a value's string representation.
.AP "const char" *string in
Null-terminated string value to append to \fIobjPtr\fR.
.AP va_list argList in
An argument list which must have been initialized using
\fBva_start\fR, and cleared using \fBva_end\fR.
.AP size_t limit in
Maximum number of bytes to be appended.
.AP "const char" *ellipsis in
Suffix to append when the limit leads to string truncation.
If NULL is passed then the suffix
.QW "..."
is used.
.AP "const char" *format in
Format control string including % conversion specifiers.
.AP int objc in
The number of elements to format or concatenate.
.AP Tcl_Obj *objv[] in
The array of values to format or concatenate.
.AP size_t newLength in
New length for the string value of \fIobjPtr\fR, not including the
final null character.

.SH DESCRIPTION
.PP
The procedures described in this manual entry allow Tcl values to
be manipulated as string values.  They use the internal representation
................................................................................
.PP
\fBTcl_AppendStringsToObj\fR is similar to \fBTcl_AppendToObj\fR
except that it can be passed more than one value to append and
each value must be a null-terminated string (i.e. none of the
values may contain internal null characters).  Any number of
\fIstring\fR arguments may be provided, but the last argument
must be a NULL pointer to indicate the end of the list.




.PP
\fBTcl_AppendLimitedToObj\fR is similar to \fBTcl_AppendToObj\fR
except that it imposes a limit on how many bytes are appended.
This can be handy when the string to be appended might be
very large, but the value being constructed should not be allowed to grow
without bound. A common usage is when constructing an error message, where the
end result should be kept short enough to be read.

Once memory debugging support has been compiled into Tcl, the C
functions \fBTcl_ValidateAllMemory\fR, and \fBTcl_DumpActiveMemory\fR,
and the Tcl \fBmemory\fR command can be used to validate and examine
memory usage.
.SH "GUARD ZONES"
.PP
When memory debugging is enabled, whenever a call to \fBTcl_Alloc\fR is
made, slightly more memory than requested is allocated so the memory
debugging code can keep track of the allocated memory, and eight-byte
.QW "guard zones"
are placed in front of and behind the space that will be
returned to the caller.  (The sizes of the guard zones are defined by the
C #define \fBLOW_GUARD_SIZE\fR and #define \fBHIGH_GUARD_SIZE\fR
in the file \fIgeneric/tclCkalloc.c\fR \(em it can
be extended if you suspect large overwrite problems, at some cost in
performance.)  A known pattern is written into the guard zones and, on
a call to \fBTcl_Free\fR, the guard zones of the space being freed are
checked to see if either zone has been modified in any way.  If one
has been, the guard bytes and their new contents are identified, and a
.QW "low guard failed"
or
.QW "high guard failed"
message is issued.  The
.QW "guard failed"
message includes the address of the memory packet and
the file name and line number of the code that called \fBTcl_Free\fR.
This allows you to detect the common sorts of one-off problems, where
not enough space was allocated to contain the data written, for
example.
.SH "DEBUGGING DIFFICULT MEMORY CORRUPTION PROBLEMS"
.PP
Normally, Tcl compiled with memory debugging enabled will make it easy
to isolate a corruption problem.  Turning on memory validation with
the memory command can help isolate difficult problems.  If you
suspect (or know) that corruption is occurring before the Tcl
interpreter comes up far enough for you to issue commands, you can set
\fBMEM_VALIDATE\fR define, recompile tclCkalloc.c and rebuild Tcl.
This will enable memory validation from the first call to
\fBTcl_Alloc\fR, again, at a large performance impact.
.PP
If you are desperate and validating memory on every call to
\fBTcl_Alloc\fR and \fBTcl_Free\fR is not enough, you can explicitly call
\fBTcl_ValidateAllMemory\fR directly at any point.  It takes a \fIchar
*\fR and an \fIint\fR which are normally the filename and line number
of the caller, but they can actually be anything you want.  Remember
to remove the calls after you find the problem.

.SH DESCRIPTION
.PP
................................................................................
source buffer is long enough such that this routine does not run off the
end and dereference non-existent or random memory; if the source buffer
is known to be null-terminated, this will not happen.  If the input is
a byte in the range 0x80 - 0x9F, \fBTcl_UtfToUniChar\fR assumes the
cp1252 encoding, stores the corresponding Tcl_UniChar in \fI*chPtr\fR
and returns 1. If the input is otherwise
not in proper UTF-8 format, \fBTcl_UtfToUniChar\fR will store the first
byte of \fIsrc\fR in \fI*chPtr\fR as a Tcl_UniChar between 0x0000 and
0x00ff and return 1.
.PP
\fBTcl_UniCharToUtfDString\fR converts the given Unicode string
to UTF-8, storing the result in a previously initialized \fBTcl_DString\fR.
You must specify \fIuniLength\fR, the length of the given Unicode string.
The return value is a pointer to the UTF-8 representation of the
Unicode string.  Storage for the return value is appended to the
end of the \fBTcl_DString\fR.
................................................................................
\fBTcl_UniCharLen\fR corresponds to \fBstrlen\fR for Unicode
characters.  It accepts a null-terminated Unicode string and returns
the number of Unicode characters (not bytes) in that string.
.PP
\fBTcl_UniCharNcmp\fR and \fBTcl_UniCharNcasecmp\fR correspond to
\fBstrncmp\fR and \fBstrncasecmp\fR, respectively, for Unicode characters.
They accept two null-terminated Unicode strings and the number of characters
to compare.  Both strings are assumed to be at least \fIuniLength\fR characters
long. \fBTcl_UniCharNcmp\fR  compares the two strings character-by-character
according to the Unicode character ordering.  It returns an integer greater
than, equal to, or less than 0 if the first string is greater than, equal
to, or less than the second string respectively.  \fBTcl_UniCharNcasecmp\fR
is the Unicode case insensitive version.
.PP
\fBTcl_UniCharCaseMatch\fR is the Unicode equivalent to
\fBTcl_StringCaseMatch\fR.  It accepts a null-terminated Unicode string,
a Unicode pattern, and a boolean value specifying whether the match should
be case sensitive and returns whether the string matches the pattern.
.PP
\fBTcl_UtfNcmp\fR corresponds to \fBstrncmp\fR for UTF-8 strings. It
accepts two null-terminated UTF-8 strings and the number of characters
to compare.  (Both strings are assumed to be at least \fIlength\fR
characters long.)  \fBTcl_UtfNcmp\fR compares the two strings
character-by-character according to the Unicode character ordering.
It returns an integer greater than, equal to, or less than 0 if the
first string is greater than, equal to, or less than the second string
respectively.
.PP
\fBTcl_UtfNcasecmp\fR corresponds to \fBstrncasecmp\fR for UTF-8
................................................................................
the start of the UTF-8 string.  If \fIsrc\fR was already at \fIstart\fR, the
return value will be \fIstart\fR.
.PP
\fBTcl_UniCharAtIndex\fR corresponds to a C string array dereference or the
Pascal Ord() function.  It returns the Tcl_UniChar represented at the
specified character (not byte) \fIindex\fR in the UTF-8 string
\fIsrc\fR.  The source string must contain at least \fIindex\fR
characters.
.PP
\fBTcl_UtfAtIndex\fR returns a pointer to the specified character (not
byte) \fIindex\fR in the UTF-8 string \fIsrc\fR.  The source string must
contain at least \fIindex\fR characters.  This is equivalent to calling
\fBTcl_UtfNext\fR \fIindex\fR times.  If \fIindex\fR is TCL_INDEX_NONE,
the return pointer points to the first character in the source string.
.PP
\fBTcl_UtfBackslash\fR is a utility procedure used by several of the Tcl
commands.  It parses a backslash sequence and stores the properly formed
UTF-8 character represented by the backslash sequence in the output
buffer \fIdst\fR.  At most \fBTCL_UTF_MAX\fR bytes are stored in the buffer.
\fBTcl_UtfBackslash\fR modifies \fI*readPtr\fR to contain the number
of bytes in the backslash sequence, including the backslash character.
The return value is the number of bytes stored in the output buffer.
.PP
See the \fBTcl\fR manual entry for information on the valid backslash
sequences.  All of the sequences described in the Tcl manual entry are
supported by \fBTcl_UtfBackslash\fR.

.sp
\fBcase\fI string \fR?\fBin\fR? {\fIpatList body \fR?\fIpatList body \fR...?}
.BE

.SH DESCRIPTION
.PP
\fINote: the \fBcase\fI command is obsolete and is supported only
for backward compatibility.  At some point in the future it may be
removed entirely.  You should use the \fBswitch\fI command instead.\fR
.PP
The \fBcase\fR command matches \fIstring\fR against each of
the \fIpatList\fR arguments in order.
Each \fIpatList\fR argument is a list of one or
more patterns.  If any of these patterns matches \fIstring\fR then
\fBcase\fR evaluates the following \fIbody\fR argument
by passing it recursively to the Tcl interpreter and returns the result
of that evaluation.
Each \fIpatList\fR argument consists of a single
pattern or list of patterns.  Each pattern may contain any of the wild-cards
described under \fBstring match\fR.  If a \fIpatList\fR
argument is \fBdefault\fR, the corresponding body will be evaluated
if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
matches \fIstring\fR and no default is given, then the \fBcase\fR
command returns an empty string.
.PP
Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
The first uses a separate argument for each of the patterns and commands;
this form is convenient if substitutions are desired on some of the
patterns or commands.
The second form places all of the patterns and commands together into
a single argument; the argument must have proper list structure, with
the elements of the list being the patterns and commands.
The second form makes it easy to construct multi-line case commands,
since the braces around the whole list make it unnecessary to include a
backslash at the end of each line.
Since the \fIpatList\fR arguments are in braces in the second form,
no command or variable substitutions are performed on them;  this makes
the behavior of the second form different than the first form in some
cases.

.TP
\fBmemory active\fR \fIfile\fR
.
Write a list of all currently allocated memory to the specified \fIfile\fR.
.TP
\fBmemory break_on_malloc\fR \fIcount\fR
.
After the \fIcount\fR allocations have been performed, \fBTcl_Alloc\fR
outputs a message to this effect and that it is now attempting to enter
the C debugger.  Tcl will then issue a \fISIGINT\fR signal against itself.
If you are running Tcl under a C debugger, it should then enter the debugger
command mode.
.TP
\fBmemory info\fR
.
Returns a report containing the total allocations and frees since
Tcl began, the current packets allocated (the current
number of calls to \fBTcl_Alloc\fR not met by a corresponding call
to \fBTcl_Free\fR), the current bytes allocated, and the maximum number
of packets and bytes allocated.
.TP
\fBmemory init \fR[\fBon\fR|\fBoff\fR]
.
Turn on or off the pre-initialization of all allocated memory
with bogus bytes.  Useful for detecting the use of uninitialized
values.
................................................................................
.
Causes a list of all allocated memory to be written to the specified \fIfile\fR
during the finalization of Tcl's memory subsystem.  Useful for checking
that memory is properly cleaned up during process exit.
.TP
\fBmemory tag\fR \fIstring\fR
.
Each packet of memory allocated by \fBTcl_Alloc\fR can have associated
with it a string-valued tag.  In the lists of allocated memory generated
by \fBmemory active\fR and \fBmemory onexit\fR, the tag for each packet
is printed along with other information about the packet.  The
\fBmemory tag\fR command sets the tag value for subsequent calls
to \fBTcl_Alloc\fR to be \fIstring\fR.
.TP
\fBmemory trace \fR[\fBon\fR|\fBoff\fR]
.
Turns memory tracing on or off.  When memory tracing is on, every call
to \fBTcl_Alloc\fR causes a line of trace information to be written to
\fIstderr\fR, consisting of the word \fITcl_Alloc\fR, followed by the
address returned, the amount of memory allocated, and the C filename
and line number of the code performing the allocation.  For example:
.RS
.PP
.CS
Tcl_Alloc 40e478 98 tclProc.c 1406
.CE
.PP
Calls to \fBTcl_Free\fR are traced in the same manner.
.RE
.TP
\fBmemory trace_on_at_malloc\fR \fIcount\fR
.
Enable memory tracing after \fIcount\fR \fBTcl_Alloc\fRs have been performed.
For example, if you enter \fBmemory trace_on_at_malloc 100\fR,
after the 100th call to \fBTcl_Alloc\fR, memory trace information will begin
being displayed for all allocations and frees.  Since there can be a lot
of memory activity before a problem occurs, judicious use of this option
can reduce the slowdown caused by tracing (and the amount of trace information
produced), if you can identify a number of allocations that occur before
the problem sets in.  The current number of memory allocations that have
occurred since Tcl started is printed on a guard zone failure.
.TP
\fBmemory validate \fR[\fBon\fR|\fBoff\fR]
.
Turns memory validation on or off. When memory validation is enabled,
on every call to \fBTcl_Alloc\fR or \fBTcl_Free\fR, the guard zones are
checked for every piece of memory currently in existence that was
allocated by \fBTcl_Alloc\fR.  This has a large performance impact and
should only be used when overwrite problems are strongly suspected.
The advantage of enabling memory validation is that a guard zone
overwrite can be detected on the first call to \fBTcl_Alloc\fR or
\fBTcl_Free\fR after the overwrite occurred, rather than when the
specific memory with the overwritten guard zone(s) is freed, which may
occur long after the overwrite occurred.

.SH DESCRIPTION
.PP
The following global variables are created and managed automatically
by the Tcl library.  Except where noted below, these variables should
normally be treated as read-only by application-specific code and by users.
.TP
................................................................................
and the value from the GetUserName() system call on Windows.
.TP
\fBwordSize\fR
.
This gives the size of the native-machine word in bytes (strictly, it
is same as the result of evaluating \fIsizeof(long)\fR in C.)
.RE
.TP
\fBtcl_precision\fR
.
This variable controls the number of digits to generate
when converting floating-point values to strings.  It defaults
to 0.  \fIApplications should not change this value;\fR it is
provided for compatibility with legacy code.
.PP
.RS
The default value of 0 is special, meaning that Tcl should
convert numbers using as few digits as possible while still
distinguishing any floating point number from its nearest
neighbours.  It differs from using an arbitrarily high value
for \fItcl_precision\fR in that an inexact number like \fI1.4\fR
will convert as \fI1.4\fR rather than \fI1.3999999999999999\fR
even though the latter is nearer to the exact value of the
binary number.
.RE
.PP
.RS
If \fBtcl_precision\fR is not zero, then when Tcl converts a floating
point number, it creates a decimal representation of at most
\fBtcl_precision\fR significant digits; the result may be shorter if
the shorter result represents the original number exactly. If no
result of at most \fBtcl_precision\fR digits is an exact representation
of the original number, the one that is closest to the original
number is chosen.
If the original number lies precisely between two equally accurate
decimal representations, then the one with an even value for the least
significant digit is chosen; for instance, if \fBtcl_precision\fR is 3, then
0.3125 will convert to 0.312, not 0.313, while 0.6875 will convert to
0.688, not 0.687. Any string of trailing zeroes that remains is trimmed.
.RE
.PP
.RS
a \fBtcl_precision\fR value of 17 digits is
.QW perfect
for IEEE floating-point in that it allows
double-precision values to be converted to strings and back to
binary with no loss of information. For this reason, you will often
see it as a value in legacy code that must run on Tcl versions before
8.5. It is no longer recommended; as noted above, a zero value is the
preferred method.
.RE
.PP
.RS
All interpreters in a thread share a single \fBtcl_precision\fR value:
changing it in one interpreter will affect all other interpreters as
well.  Safe interpreters are not allowed to modify the
variable.
.RE
.PP
.RS
Valid values for \fBtcl_precision\fR range from 0 to 17.
.RE
.TP
\fBtcl_rcFileName\fR
.
This variable is used during initialization to indicate the name of a
user-specific startup file.  If it is set by application-specific
initialization, then the Tcl startup code will check for the existence
of this file and \fBsource\fR it if it exists.  For example, for \fBwish\fR
the variable is set to \fB~/.wishrc\fR for Unix and \fB~/wishrc.tcl\fR
for Windows.
.TP
\fBtcl_traceCompile\fR
.
The value of this variable can be set to control
how much tracing information
is displayed during bytecode compilation.
By default, \fBtcl_traceCompile\fR is zero and no information is displayed.

 *	If a command named "cmdName" already exists for interp, it is
 *	first deleted.  Then the new command is created from the arguments.

 *
 *	In the future, during bytecode evaluation when "cmdName" is seen as
 *	the name of a command by Tcl_EvalObj or Tcl_Eval, the object-based
 *	Tcl_ObjCmdProc proc will be called. When the command is deleted from
 *	the table, deleteProc will be called. See the manual entry for details
 *	on the calling sequence.
