Name
       fread, fwrite - buffered binary input/output

Syntax
       #include <stdio.h>

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

       size_t fwrite(ptr, size, nitems, stream)
       void *ptr;
       size_t size, nitems;
       FILE *stream;

Description
       The  function  reads  into a block beginning at ptr, nitems of data of the size size (usually sizeof *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 to satisfy the

       The function appends, at most, nitems of data of the size size (usually sizeof *ptr) beginning at ptr  to  the  named  output  stream.	It
       returns the number of items actually written.

Return Values
       The and functions return 0 upon end of file or error.
