NAME
explain_fread_or_die - binary stream input and report errors
SYNOPSIS
#include <libexplain/fread.h >
void explain_fread_or_die(void *ptr, size_t size, size_t nmemb, FILE *fp);
DESCRIPTION
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 numebr read or 0 on
end-of-input.
On failure, prints an explanation and exits.
