NAME

       explain_malloc_or_die - Allocate and free dynamic memory and report errors

SYNOPSIS

       #include <libexplain/malloc.h>
       void *explain_malloc_or_die(size_t size);

DESCRIPTION

       The  explain_malloc_or_die  function  is  used  to  call  the  malloc(3) system call.  On failure an explanation will be printed to stderr,
       obtained from explain_malloc(3), and then the process terminates by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
	      void *result = explain_malloc_or_die(size);

       size    The size, exactly as to be passed to the malloc(3) system call.

       Returns:
	       This function only returns on success.  On failure, prints an explanation and exits.
