示例1: transmit_file
void transmit_file(tcp::socket& socket,
random_access_handle& file, Handler handler)
{
// Construct an OVERLAPPED-derived object to contain the handler.
overlapped_ptr overlapped(socket.get_io_service(), handler);
// Initiate the TransmitFile operation.
BOOL ok = ::TransmitFile(socket.native_handle(),
file.native_handle(), 0, 0, overlapped.get(), 0, 0);
DWORD last_error = ::GetLastError();
// Check if the operation completed immediately.
if (!ok && last_error != ERROR_IO_PENDING)
{
// The operation completed immediately, so a completion notification needs
// to be posted. When complete() is called, ownership of the OVERLAPPED-
// derived object passes to the io_service.
boost::system::error_code ec(last_error,
boost::asio::error::get_system_category());
overlapped.complete(ec, 0);
}
else
{
// The operation was successfully initiated, so ownership of the
// OVERLAPPED-derived object has passed to the io_service.
overlapped.release();
}
