.SH NAME
Tcl_DumpActiveMemory, Tcl_InitMemory, Tcl_ValidateAllMemory \- Validated memory allocation interface
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
int
\fBTcl_DumpActiveMemory\fR(\fIfileName\fR)
.sp
void
\fBTcl_InitMemory\fR(\fIinterp\fR)
.sp
void
\fBTcl_ValidateAllMemory\fR(\fIfileName, line\fR)

.SH ARGUMENTS
.AS Tcl_Interp *fileName
.AP Tcl_Interp *interp in
Tcl interpreter in which to add commands.
.AP "const char" *fileName in
For \fBTcl_DumpActiveMemory\fR, name of the file to which memory
information will be written.  For \fBTcl_ValidateAllMemory\fR, name of
the file from which the call is being made (normally \fB__FILE__\fR).
.AP int line in
Line number at which the call to \fBTcl_ValidateAllMemory\fR is made
(normally \fB__LINE__\fR).
.BE

.SH DESCRIPTION
These functions provide access to Tcl memory debugging information.
They are only functional when Tcl has been compiled with
\fBTCL_MEM_DEBUG\fR defined at compile-time.  When \fBTCL_MEM_DEBUG\fR
is not defined, these functions are all no-ops.
.PP
\fBTcl_DumpActiveMemory\fR will output a list of all currently
allocated memory to the specified file.  The information output for
each allocated block of memory is:  starting and ending addresses
(excluding guard zone), size, source file where \fBTcl_Alloc\fR was
called to allocate the block and line number in that file.  It is
especially useful to call \fBTcl_DumpActiveMemory\fR after the Tcl
interpreter has been deleted.
.PP
\fBTcl_InitMemory\fR adds the Tcl \fBmemory\fR command to the
interpreter given by \fIinterp\fR.  \fBTcl_InitMemory\fR is called
by \fBTcl_Main\fR.
.PP
\fBTcl_ValidateAllMemory\fR forces a validation of the guard zones of
all currently allocated blocks of memory.  Normally validation of a
block occurs when its freed, unless full validation is enabled, in
which case validation of all blocks occurs when \fBTcl_Alloc\fR and
\fBTcl_Free\fR are called.  This function forces the validation to occur
at any point.
