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

       malloc(3), malloc_hook(3)

COLOPHON

       This page is part of release 3.27 of the Linux man-pages project.  A description of the project, and information about reporting bugs,  can
