FREAD(3S)                                               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.

          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.
