muntrace
MTRACE(3) Linux Programmer's Manual MTRACE(3)
NAME
mtrace, muntrace - malloc debugging
SYNOPSIS
#include <mcheck.h>
void mtrace(void);
void muntrace(void);
DESCRIPTION
The function mtrace() installs handlers for malloc(), realloc() and
free(). The function muntrace() disables these handlers.
The environment variable MALLOC_TRACE defines a file where mtrace()
writes its output. This file must be writable to the user or mtrace()
will do nothing. If the file is not empty it will be truncated.
NOTE
The output of mtrace() will be ASCII but not in a friendly format. So
glibc comes with a perl-script call mtrace to make sense of it.
CONFORMS TO
These are GNU extensions.
