                                                                                        explain_calloc_or_die(3)

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

       The explain_calloc_on_error function is used to call the calloc(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_calloc(3) function, but still returns to the caller.

       nmemb   The nmemb, exactly as to be passed to the calloc(3) system call.

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

       The explain_calloc_or_die function is intended to be used in a fashion similar to the following example:
              void *result = explain_calloc_or_die(nmemb, size);

       explain_calloc_or_die - Allocate and clear memory and report errors

       The  explain_calloc_or_die  function  only  returns  on  success,  see calloc(3) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_calloc_on_error function always returns the value return  by  the  wrapped  calloc(3)  system
       call.
