FREAD(3S)	    UNIX Programmer's Manual		FREAD(3S)


NAME
     fread, fwrite - buffered binary input/output

SYNOPSIS
     #include <stdio.h>

     fread(ptr, sizeof(*ptr), nitems, stream)
     FILE *stream;

     fwrite(ptr, sizeof(*ptr), nitems, stream)
     FILE *stream;

DESCRIPTION
     Fread reads, into a block beginning at ptr, nitems of data
     of the type of *ptr from the named input stream.  It returns
     the number of items actually read.

     If stream is stdin and the standard output is line buffered,
     then any partial output line will be flushed before any call
     to read(2) to satisfy the fread.

     Fwrite appends at most nitems of data of the type of *ptr
     beginning at ptr to the named output stream.  It returns the
     number of items actually written.

SEE ALSO
     read(2), write(2), fopen(3S), getc(3S), putc(3S), gets(3S),
     puts(3S), printf(3S), scanf(3S)

DIAGNOSTICS
     Fread and fwrite return 0 upon end of file or error.
