mtrace, muntrace — malloc debugging
#include <mcheck.h>
void
mtrace( |
void) ; |
void
muntrace( |
void) ; |
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.
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.
