[alsa-devel] to get the detail information of a codec

Hi all,
Now I'm writing a program which can list some capabilities of my
codec, such as what rates and formats my codec supports.
By typing 'cat /proc/asound/card0/codec#0', you can see the
detail of your card. I want to write a program which can show
these information by alsa-lib. However, I couldn't find a function
in alsa-lib which can tell me the formats and rates. Is there a
way to get this detail?
By the way, my card is intel-hda and the codec is alc268.
Another question is I've seen the word "element" in many
function, such as snd_ctl_event_elem_get_device. What
"element" means in alsa world? I couldn't find any artile
mentioning it!!!
Thanks all!!!
