13 fwrite(buffer, size, number, stream) -- write 'number' items of sixe
14 'size' bytes from 'buffer' onto 'stream'. Returns the number of items
15 written. If 'number' or 'size' is negative, nothing is written, and
16 0 is returned. EOF may cause the last item written to be imcomplete.
17 Check with feof() to detect an EOF condition. Use ferror() to check
18 for error conditions.
