NAME mtrace, muntrace - malloc debugging CONTENTS Synopsis Description Note SYNOPSIS "#include <mcheck.h>" "void mtrace(void);" "void muntrace(void);" DESCRIPTION The function mtrace() installs handlers for malloc(), realloc() and free(). 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. NOTE 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. "CONFORMS TO" These are GNU extensions. "SEE ALSO" malloc(3), malloc_hook(3)
