| void Alsa::Main | ( | void | ) | [private, virtual] |
Main method for driver thread.
drivers have their own thread of execution, created using StartThread(); this is the entry point for the driver thread, and must be overloaded by all threaded drivers.
Implements ThreadedDriver.
References Driver::InQueue, PLAYER_WARN1, and Driver::ProcessMessages().
| void Alsa::MainQuit | ( | void | ) | [private, virtual] |
Cleanup method for driver thread (called when main exits)
Overload this method and to do additional cleanup when the driver thread exits.
Reimplemented from ThreadedDriver.
References PLAYER_WARN.
| int Alsa::ProcessMessage | ( | QueuePointer & | resp_queue, |

| ) | [virtual] |
Message handler.
This function is called once for each message in the incoming queue. Reimplement it to provide message handling. Return 0 if you handled the message and -1 otherwise
- Parameters:
-
resp_queue The queue to which any response should go. hdr The message header data The message body
Reimplemented from Driver.
