explain_calloc_or_die - Allocate and clear memory and report errors
#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);
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.
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.
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);
