    FREAD(3)            Linux Programmer's Manual            FREAD(3)

    NAME
           fread, fwrite - binary stream input/output

    SYNOPSIS
           #include <stdio.h>

           int  fread(  void  *ptr,  size_t  size, size_t nmemb, FILE
           *stream);

           int fwrite( 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.

    RETURN VALUES
           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.

### SEE ALSO

feof, ferror, read, write,

    STANDARDS
           The functions fread and fwrite conform to ANSI C3.159-1989
           (``ANSI C'').
