NAME

6       mtrace, muntrace - malloc debugging
7

SYNOPSIS

9       #include <mcheck.h>
10
11       void mtrace(void);
12
13       void muntrace(void);
14

DESCRIPTION

16       The  function  mtrace() installs handlers for malloc(3), realloc(3) and
17       free(3).  The function muntrace() disables these handlers.
18       The environment variable MALLOC_TRACE defines  a  file  where  mtrace()
19       writes  its output.  This file must be writable to the user or mtrace()
20       will do nothing.  If the file is not empty it will be truncated.
21

CONFORMING TO

23       These are GNU extensions.
24

NOTES

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