#include <stdio.h>

size_t fwrite( void *buf, size_t size, size_t n, FILE *stream );

  <buf> is an array with (at least) <n> elements.
  <size> is the size of each element: <size> = sizeof(buf[0])
  <n> is the number of elements in <buf> (to be written).
  <stream> is an open stream (see fopen).


Function writes <size> * <n> bytes from array <buf>. 
It returns the number of bytes written (error if < size * n).
