Purpose： Use _fwrite to write a specified number of data itmes, each of a given size,
from a buffer to the current position in a file opened for buffered output. The
current position is updated after the write.
Syntax：
size_t _fwrite(const void *buffer, size_t size, size_t count, _TFILE
*file_pointer);
Example call：
numwrite = _fwrite(buffer, sizeof(char), 80, outfile);
Includes：
#include “SDK.h”
Description：
The _fwrite function writes count data items, each of size bytes, to the file
specified by the argument file_pointer, starting at the current position. After
the write operation is complete, the current position is updated. The data to
be written is in the buffer whose address is passed to _fwrite in the
argument buffer.
Returns： The _fwrite function returns the number of items it actually wrote.
