FREAD(3) Linux Programmer's Manual FREAD(3)
NAME
fread, fwrite - binary stream input/output
SYNOPSIS
#include <stdio.h>
size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream);
size_t fwrite(const void *ptr, size_t size, size_t nmemb,
FILE *stream);
DESCRIPTION
The function fread() reads nmemb elements of data, each size bytes long, from the
stream pointed to by stream, storing them at the location given by ptr.
The function fwrite() writes nmemb elements of data, each size bytes long, to the
stream pointed to by stream, obtaining them from the location given by ptr.
For nonlocking counterparts, see unlocked_stdio(3).
RETURN VALUE
fread() and fwrite() return the number of items successfully read or written
(i.e., not the number of characters). If an error occurs, or the end-of-file is
reached, the return value is a short item count (or zero).
fread() does not distinguish between end-of-file and error, and callers must use
feof(3) and ferror(3) to determine which occurred.
CONFORMING TO
C89, POSIX.1-2001.
