explain_fread_or_die3
Binary stream input and report errors
Usage
#include <libexplain/fread.h>
void explain_fread_or_die(void *ptr, size_t size, size_t nmemb, FILE *fp);
Overview
The explain_fread_or_die function is used to call the fread(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fread(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 how_many = explain_fread_or_die(ptr, size, nmemb, fp);- ptr
-
The ptr, exactly as to be passed to the fread(3) system call.
- size
-
The size, exactly as to be passed to the fread(3) system call.
- nmemb
-
The nmemb, exactly as to be passed to the fread(3) system call.
- fp
-
The fp, exactly as to be passed to the fread(3) system call.
- Returns:
-
This function only returns on success, the number read or 0 on end‐of‐input. On failure, prints an explanation and exits.
