Is snd_pcm_poll_descriptors_revents() more than
an
accessor ? If it is, the name is a quite misleading.
To answer my own question, it seems that it *is* more
than an accessor.
The docs leave one thing unclear. Does this call require
an array of unsigned short int (one per pollfd), or are
events from all pollfds combined into one revents value? In that case, how can one test if *all* pollfd for a
given
pcm are ready ?
You cannot. The state of the file descriptors is not necessarily
related to the state of the PCM device (which is why this function
exists).
