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


these macros are redefined to be special debugging versions
of these procedures.  To support Tcl's memory debugging within a

Note that the current escape resp. quoting of arguments for windows works only
with executables using CommandLineToArgv, CRT-library or similar, as well as
with the windows batch files (excepting the newline, see below).
Although it is the common escape algorithm, but, in fact, the way how the
executable parses the command-line (resp. splits it into single arguments)
is decisive.
.PP
Unfortunately, there is currently no way to supply newline character within 
an argument to the batch files (\fB.cmd\fR or \fB.bat\fR) or to the command 
processor (\fBcmd.exe /c\fR), because this causes truncation of command-line
(also the argument chain) on the first newline character. 
But it works properly with an executable (using CommandLineToArgv, etc).

that memory is properly cleaned up during process exit.

\fBmemory tag\fR \fIstring\fR

Each packet of memory allocated by \fBckalloc\fR can have associated
with it a string-valued tag.  In the lists of allocated memory generated

to \fBckalloc\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 \fBckalloc\fR causes a line of trace information to be written to

address returned, the amount of memory allocated, and the C filename

Enable memory tracing after \fIcount\fR \fBckalloc\fRs have been performed.
For example, if you enter \fBmemory trace_on_at_malloc 100\fR,
after the 100th call to \fBckalloc\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 \fBckalloc\fR or \fBckfree\fR, the guard zones are
checked for every piece of memory currently in existence that was
allocated by \fBckalloc\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 \fBckalloc\fR or
\fBckfree\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.
