explain_calloc_or_die(3)				     Library Functions Manual					  explain_calloc_or_die(3)

NAME
       explain_calloc_or_die - Allocate and clear memory and report errors

SYNOPSIS
       #include <libexplain/calloc.h>
       void *explain_calloc_or_die(size_t nmemb, size_t size);
       void *explain_calloc_on_error(size_t nmemb, size_t size);

DESCRIPTION
       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.

RETURN VALUE
       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.

EXAMPLE
       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);

SEE ALSO
