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 infor‐ mation. 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 cal‐ loc(3) system call.
EXAMPLE The explain_calloc_or_die function is intended to be used in a fashion similar to the fol‐ lowing example: void *result = explain_calloc_or_die(nmemb, size);
