My alsashmrec uses kill((pid_t)diskpid,SIGSTOP); (in disk writer process) and kill((pid_t)diskpid,SIGCONT); (in A/D reader process) Perhaps that could be replaced with semaphore but what if multiple processes uses the same disk service process? That increases the number of SIGCONTs but otherwise the processes would be uncoupled. How it is with semaphores? >- How should the ringbuffer be initilized when starting to play? Fill it up if its size was selected optimally. If you have multiple songs and you don't know which the user would like to play next, then make one ringbuffer per song and fill them all up. Then the playing can start instantly when user presses the song button. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software
