◆ mainloop()

void vrpn_Nikon_Controls::mainloop ( void )
virtual

This routine is called each time through the server's main loop.

It will take a course of action depending on the current status of the device, either trying to reset it or trying to get a reading from it. It will try to reset the device if no data has come from it for a couple of seconds.

Implements vrpn_BaseClass.
