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 loca‐
       tion 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 loca‐
       tion given by ptr.

       For non-locking 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.
