explain_fwrite_or_die — binary stream output and report errors
size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp);
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
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);
The ptr, exactly as to be passed to the fwrite(3) system call.
The size, exactly as to be passed to the fwrite(3) system call.
The nmemb, exactly as to be passed to the fwrite(3) system call.
The fp, exactly as to be passed to the fwrite(3) system call.
This function only returns on success. On failure, prints an explanation and exits.
