FREAD(3S)               GENIX 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(3),  getc(3),  putc(3),  gets(3),  puts(3),
           printf(3), scanf(3)

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