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.
