CsoundPerformanceThread Class Reference

#include <csPerfThread.hpp>

List of all members.


Detailed Description

CsoundPerformanceThread(Csound *) CsoundPerformanceThread(CSOUND *)

Performs a score in a separate thread until the end of score is reached, the playback (which is paused by default) is stopped by calling CsoundPerformanceThread::Stop(), or an error occurs. The constructor takes a Csound instance pointer as argument; it assumes that csoundCompile() was called successfully before creating the performance thread. Once the playback is stopped for one of the above mentioned reasons, the performance thread calls csoundCleanup() and returns.

An example program using the CsoundPerformanceThread class

include <stdio.h> include "csound.hpp" include "csPerfThread.hpp"

int main(int argc, char *argv[]) { int result=0; Csound cs; csoundInitialize(NULL,NULL,NULL); result = cs.Compile(argc,argv);

if(!result) { CsoundPerformanceThread perfThread(cs.GetCsound()); perfThread.Play(); // Starts performance while(perfThread.GetStatus() == 0); // nothing to do here... but you could process input events, graphics etc perfThread.Stop(); // Stops performance. In fact, performance should have already been finished, so this is just an example of how to stop if you need perfThread.Join(); // always call Join() after Stop() as a rule of thumb. } else{ printf("csoundCompile returned an error\n"); return 1; }

return 0; }
