explain_fwrite_or_die − binary stream output and report errors
#include <libexplain/fwrite.h>
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 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.
