explain_fread_or_die − binary stream input and report errors
#include <libexplain/fread.h>
void explain_fread_or_die(void *ptr, size_t size, size_t nmemb, FILE *fp);
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.
