SYNOPSIS

#include <libexplain/fwrite.h>

size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp);

DESCRIPTION

The B]explain_fwrite_or_die function is used to call the I]fwrite(3) system call. On failure an explanation will be printed to I]stderr, obtained from I]explain_fwrite(3), and then the process terminates by calling CW]exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

size_t result = explain_fwrite_or_die(ptr, size, nmemb, fp);

I]ptr The ptr, exactly as to be passed to the I]fwrite(3) system call.
I]size The size, exactly as to be passed to the I]fwrite(3) system call.
I]nmemb The nmemb, exactly as to be passed to the I]fwrite(3) system call.
I]fp The fp, exactly as to be passed to the I]fwrite(3) system call.
Returns: This function only returns on success. On failure, prints an explanation and exits.
