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(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.

SEE ALSO
