alsaloop: confusing line of code and easier example of the use of snd_pcm_poll_descriptors API
by GitHub issues - edited 23 Dec '22

23 Dec '22

alsa-project/alsa-utils issue #185 was edited from anthonio9: Hi! Recently I've been studying the `alsaloop` software, I'm trying to understand how should the `snd_pcm_poll_descriptors` api be used reliably. Reading through the `pcmjob.c` file I've noticed that in the `pcmjob_pollfds_handle` function in line 1964 there's a condition that does not exactly make sense to me. What's the purpose of variable `loopcount`? If the code is more or less ```cpp int loopcount = 0; do { // instructions loopcount++; } while ((ccount > 0 || pcount > 0) && loopcount > 10); // line 1964 ``` isn't it equal to running the loop just once without any loops? After all, the `loopcount` will never reach 10 and the conditional statement will always turn false finishing the loop after one iteration. Correct me if I'm wrong. I suppose that condition would make more sense if it was as below: ```cpp } while ((ccount > 0 || pcount > 0) && loopcount < 10); // line 1964 ``` then the loop would be stop for iterating too many times, assuming that 10 is "too many". With the part `loopcount < 10` deleted, the loop usually runs twice. I'd also appreciate a simpler example than `alsaloop` focusing just on the audio parts, on transferring audio from input to output reliably with the use of `snd_pcm_poll_descriptors`.

I am preparing v2 of this series, but I don't see these changes on drm-next, which seems to have been updated to at least 6.2-rc1. I tried searching for these changes on lore [1], but I don't see them there either.

[PATCH V7 0/5] ASoC: codecs: Add Awinic AW883XX audio amplifier driver
