Functions

audioThread void audioThread(): Undocumented in source. Be warned that the author may not have intended to support it.
runAudioThread int runAudioThread(): Undocumented in source. Be warned that the author may not have intended to support it.
suspendAudioThread int suspendAudioThread(): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

alsaerrCode int alsaerrCode;: Contains the last ALSA specific error code.
buffer ubyte[] buffer;: Buffer for outputting audio data.
bufferSize uint bufferSize;: Contains buffer size in samples.
dev ALSADevice dev;: Due to how ALSA works, the pcm handle is accessed from there directly, also keeps a reference of it to avoid calling the destructor.

Inherited Members

From OutputStream

_threadID ThreadID _threadID;: The ID of the audio thread if there's any.
errCode int errCode;: The last error code that was encountered, or 0 if none.
statusCode uint statusCode;: Internal state flags.
StatusFlags enum StatusFlags: Undocumented in source.
threadID ThreadID threadID [@property getter]: Returns the thread ID of the stream thread. Warning: It is not advised to join this thread.
callback_buffer void delegate(ubyte[] buffer) callback_buffer;: Called periodically request more data to device output. Target must not call any functions that either suspend the thread, or would impact real-time performance (disk operations, etc).
callback_onBufferUnderflow void delegate() callback_onBufferUnderflow;: Called when a buffer underflow error have occured. (Optional)
runAudioThread int runAudioThread(): Runs the audio thread. This either means that it'll create a new low-level thread to feed the stream a steady amount of data, or use whatever the backend on the OS has.
suspendAudioThread int suspendAudioThread(): Suspends the audio thread by allowing it to escape normally and close things safely, or suspending it on the backend.
