Tcl_DumpActiveMemory(3) Tcl Library Procedures Tcl_DumpActiveMemory(3)______________________________________________________________________________NAME
Tcl_DumpActiveMemory, Tcl_InitMemory, Tcl_ValidateAllMemory - Validated
memory allocation interface.
SYNOPSIS
#include <tcl.h>
int
Tcl_DumpActiveMemory(fileName)
void
Tcl_InitMemory(interp)
void
Tcl_ValidateAllMemory(fileName, line)
ARGUMENTS
Tcl_Interp *interp (in) Tcl interpreter in which to
add commands.
char *fileName (in) For Tcl_DumpActiveMemory,
name of the file to which
memory information will be
written. For Tcl_Vali‐
dateAllMemory, name of the
file from which the call is
being made (normally
__FILE__).
int line (in) Line number at which the call
to Tcl_ValidateAllMemory is
made (normally __LINE__).
_________________________________________________________________DESCRIPTION
These functions provide access to Tcl memory debugging information.
They are only available when Tcl has been compiled with TCL_MEM_DEBUG
defined at compile-time.
Tcl_DumpActiveMemory will output a list of all currently allocated mem‐
ory 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 ckalloc was called to allocate the block
and line number in that file. It is especially useful to call
Tcl_DumpActiveMemory after the Tcl interpreter has been deleted.
Tcl_InitMemory adds the Tcl memory command to the interpreter given by
interp. It is called by Tcl_Main when Tcl has been compiled with
TCL_MEM_DEBUG defined.
Tcl_ValidateAllMemory 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 ckalloc and ckfree are called.
This function forces the validation to occur at any point.
