Usage
#include <libexplain/fwrite.h>
size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp);
Overview
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 following 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.
