No, but if you have different parts of your code trying to use SIGALARM, then you are doomed ! I don't know if the codec engine does, but it sure looks like it. > > Is there a better way to do accurate timing (20 msec) than with interval > timers? > Maybe using thread and semaphore etc... is the only options you have left if you can't use any SIGALARM messing call (setitimer, sleep, usleep....) Then if you want a timeout, you can do so with the timeout arg of a select call, where all three sets are empty. > Thanks, > Danny > _______________________________________________ > Davinci-linux-open-source mailing list > Davinci-linux-open-source@linux.davincidsp.com > http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source > > _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
