MTRACE(3)                     Linux Programmer's Manual                     MTRACE(3)

NAME         top

       mtrace, muntrace - malloc debugging

SYNOPSIS         top

       #include <mcheck.h>

       void mtrace(void);

       void muntrace(void);

DESCRIPTION         top

       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         top

       These are GNU extensions.

NOTES         top

       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.
