Expand description

Initialize the AudioSession.

This function has to be called once before calling any other AudioSession functions.

Parameter inRunLoop: A CFRunLoopRef indicating the desired run loop the interruption routine should be run on. Pass NULL to use the main run loop.

Parameter inRunLoopMode: A CFStringRef indicating the run loop mode for the runloop where the completion routine will be executed. Pass NULL to use kCFRunLoopDefaultMode.

Parameter inInterruptionListener: An AudioSessionInterruptionListener to be called when the AudioSession is interrupted.

Parameter inClientData: The client user data to use when calling the interruption listener.

§Safety

  • in_run_loop possibly has additional threading requirements.
  • in_run_loop might not allow None.
  • in_run_loop_mode might not allow None.
  • in_interruption_listener must be implemented correctly.
  • in_client_data must be a valid pointer.
