[alsa-devel] non-blocking mode example

[ThomasJF]

Thanks Clemens,

it is really not a small example and an uneven path to go through the 
whole files... But may be you or someone else could answer my short 
questions? I have read a file to buffer with "allframes".

1.) Do I use snd_pcm_writei(...) with a size of "allframes" or loop it 
with smaller packages (periodsize)

2.) What are the actual functions to get the interrupt and send the 
frames needed into the ringbuffer (standard I/O or select)?

If you start with ALSA you will find enough pieces of code. But it is 
not very clear, because many pieces of cake are done with much elder 
APIs from ALSA...

Best regards
Thomas
