示例1: writeFileClosure
/**
* Writes the data size to the header and a CRC checksum at the end.
* @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;
$this->writer->writeUInt32LE($data_size);
// Does not include file header or crc. Little endian format.
//write 2 byte crc check at end of file
$this->writer->setOffset($offset);
$this->writer->writeUInt16LE(0);
return $this;
