NAME

       mtrace, muntrace - malloc debugging

SYNOPSIS

       #include <mcheck.h>

       void mtrace(void);

       void muntrace(void);

DESCRIPTION

       The  function  mtrace() installs handlers for malloc(3), realloc(3) and
       free(3).  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.

CONFORMING TO

       These are GNU extensions.

NOTES

       The output of mtrace() will be ASCII but not in a friendly format.   So
       glibc comes with a perl-script called mtrace to make sense of it.
