.BS
.SH NAME
Tcl_SetObjResult, Tcl_GetObjResult, Tcl_SetResult, Tcl_GetStringResult, Tcl_AppendResult, Tcl_AppendElement, Tcl_ResetResult, Tcl_TransferResult, Tcl_FreeResult \- manipulate Tcl result
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
\fBTcl_SetObjResult\fR(\fIinterp, objPtr\fR)
.sp
Tcl_Obj *

\fBTcl_AppendResult\fR(\fIinterp, result, result, ... , \fB(char *) NULL\fR)
.sp
\fBTcl_ResetResult\fR(\fIinterp\fR)
.sp
\fBTcl_TransferResult\fR(\fIsourceInterp, code, targetInterp\fR)
.sp
\fBTcl_AppendElement\fR(\fIinterp, element\fR)
.sp
\fBTcl_FreeResult\fR(\fIinterp\fR)
.SH ARGUMENTS
.AS Tcl_FreeProc sourceInterp out
.AP Tcl_Interp *interp out
Interpreter whose result is to be modified or read.
.AP Tcl_Obj *objPtr in
Tcl value to become result for \fIinterp\fR.
.AP char *result in

However if the new list element is the first in a list or sub-list
(i.e. \fIinterp\fR's current result is empty, or consists of the
single character
.QW { ,
or ends in the characters
.QW " {" )
then no space is added.
.PP
\fBTcl_FreeResult\fR performs part of the work
of \fBTcl_ResetResult\fR.
It frees up the memory associated with \fIinterp\fR's result.
It also sets \fIinterp->freeProc\fR to zero, but does not
change \fIinterp->result\fR or clear error state.
\fBTcl_FreeResult\fR is most commonly used when a procedure
is about to replace one result value with another.
.SH "THE TCL_FREEPROC ARGUMENT TO TCL_SETRESULT"
.PP
\fBTcl_SetResult\fR's \fIfreeProc\fR argument specifies how
the Tcl system is to manage the storage for the \fIresult\fR argument.
If \fBTcl_SetResult\fR or \fBTcl_SetObjResult\fR are called
at a time when \fIinterp\fR holds a string result,
they do whatever is necessary to dispose of the old string result
