explain_fwrite_or_die(3) Library Functions Manual explain_fwrite_or_die(3) NAME explain_fwrite_or_die - binary stream output and report errors SYNOPSIS #include <libexplain/fwrite.h> size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp); DESCRIPTION The explain_fwrite_or_die function is used to call the fwrite(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fwrite(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the fol- lowing example: size_t result = explain_fwrite_or_die(ptr, size, nmemb, fp); ptr The ptr, exactly as to be passed to the fwrite(3) system call. size The size, exactly as to be passed to the fwrite(3) system call. nmemb The nmemb, exactly as to be passed to the fwrite(3) system call. fp The fp, exactly as to be passed to the fwrite(3) system call. Returns: This function only returns on success. On failure, prints an explanation and exits.
