Thank you for the reply, Takashi.

The problem is, I'm not sure what should I loop through. I saw this list on the wiki ( http://www.alsa-project.org/main/index.php/DeviceNames ) but I don't know how it was obtained.

The code would be like:

int card = -1; while (!snd_card_next(&card) && card >= 0) { ... }

Hi,

I am trying to develop an application using the ALSA library. I read in a book about the snd_cards function, but it doesn't seem to be defined anywhere. (The book is rather old, though, it talks about the 0.5.x series).

The compiler doesn't complain, but the linker gives me an "undefined reference to `snd_cards'" error. I assume this function is deprecated, but what can I use instead?

Oh that myth. I myself already forgot about that function :)

On ALSA 1.x, there is no corresponding function. You'll need to loop and check the presence of each card.
