[ i thought sent a message about this earlier, but didn't see it ] i was looking at the "full duplex poll" code that jaroslav provided for josh. i noticed that it doesn't expect or require to find that read+write are possible at the same time.
do we have any expectation of generally supporting synchronous full duplex operation - that is, there will always be a point in time when a certain number of frames (preferably period_size, but perhaps not) can be read *and* written ? all the examples of code that i've seen far that do "full duplex" don't do what i would call "full duplex" - they require separate code pathways to handle read and write, and these code pathways never execute in parallel, or interleaved. --p _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
