Member Function Documentation

void snd::Main ( ) [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 PLAYER_MSG0, Driver::ProcessMessages(), and ThreadedDriver::Wait().

int snd::ProcessMessage ( QueuePointer resp_queue,
player_msghdr hdr,
void *  data 
) [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

resp_queueThe queue to which any response should go.
hdrThe message header
dataThe message body

Reimplemented from Driver.

int snd::Setup ( ) [virtual]

Initialize the driver.

This function is called with the first client subscribes; it MUST be implemented by the driver.

Returns 0 on success.

Reimplemented from ThreadedDriver.

References PLAYER_MSG0.

int snd::Shutdown ( ) [virtual]

Finalize the driver.

This function is called with the last client unsubscribes; the default version simple stops the driver thread if one is present. In this case resources should be cleaned up in MainQuit.

Returns 0 on success.

Reimplemented from ThreadedDriver.

References Driver::InQueue, PLAYER_MSG0, ThreadedDriver::StopThread(), and Device::Unsubscribe().
