#include <jmixer.h>
Collaboration diagram for Stream_mixer:
Everything is connected to Stream_mixer: the instance of this class controls all existent input and output channels attached to it, plus it holds the file descriptors for the soundcard and all the necessary private buffers of MuSE.
The Stream_mixer runs thru the cafudda() function which should be always called from the main (parent) thread of your program.
Child threads are spawned by some of the public functions offered by this class, anyway you don't have to take care of those issues.

THIS IS THE MAIN MIXING PROCEDURE: CAFUDDA! Cafudda should be repeatedly called by the main process. It doesn't fills up the CPU load so there is no need to wait or do any time syncronizing, it is just all done inside. Call it repeatedly after launching all the GUI threads and setting up the engine to act as you like, then while running on the main process the mixer can still be used by interface threads. see main.cpp for an example of its use.
