Function Documentation

VOID cbmiec_wait_for_listener (  IN PDEVICE_EXTENSION  Pdx, IN BOOLEAN  SendEoi )

Wait until listener is ready to receive. This function waits until a listener is ready. Parameters: Pdx  Pointer to the device extension. SendEoi  TRUE if we want to signal an EOI. FALSE otherwise. Todo: Shouldn't we make sure that there is no spurious interrupt until now? Bug: This implementation can lock up the while machine, thus, do not use it! Definition at line 81 of file waitlistener.c.
