Re: [alsa-devel] snd_mixer handle in two threads

Hello again

This is still about the alsamixer-qt4 application I working on.

This time I wonder if a snd_mixer_t handle created with snd_mixer_open ( ... ) can be used in two threads concurrently.

One thread should be the main Qt4 GUI thread and the second thread should only poll ( ... ) blocking for ALSA events on the shared snd_mixer_t handle in accompany with

snd_mixer_poll_descriptors_count ( ... ) snd_mixer_poll_descriptors ( ... ) snd_mixer_poll_descriptors_revents ( ... )

The second thread then will post Qt4 signals to the main thread on occassion.

Nevermind, QSocketNotifier solved the issue in a better way.
