Protos / protoSoundChannel

Close

soundChannel:Close()

Closes an open sound channel.

return value

Undefined; do not rely on it.

DISCUSSION

This method frees the system resources allocated for the sound channel. It throws the exception |evt.ex.fr| if an error occurs.

IMPORTANT

The operating system memory allocated for a sound channel by the Open method is not released when the soundChannel frame is garbage-collected. You must call the *Close method explicitly to free this memory and avoid memory leaks.
