Member Function Documentation

◆ Action()

void cDvbTuner::Action ( void )

privatevirtual

A derived cThread class must implement the code it wants to execute as a separate thread in this function.

If this is a loop, it must check Running() repeatedly to see whether it's time to stop.

Implements cThread.
