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 com-
mands.
const 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 (nor-
mally __FILE__).
int line (in) Line number at which the call to
Tcl_ValidateAllMemory is made (nor-
mally __LINE__).

DESCRIPTION
These functions provide access to Tcl memory debugging information.
They are only functional when Tcl has been compiled with TCL_MEM_DEBUG
defined at compile-time. When TCL_MEM_DEBUG is not defined, these
functions are all no-ops.
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. Tcl_InitMemory is called by Tcl_Main.
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.
