示例1: writeFileClosure

* @return \Fit\Writer
*/
protected function writeFileClosure()
{
//mark current writing position
$offset = $this->writer->getOffset();
//move to header and write the size of the data
$this->writer->setOffset(4);
$data_size = $this->writer->getSize() - 14;

// Does not include file header or crc. Little endian format.
//write 2 byte crc check at end of file
