For some example code, you could grab the clalsadrv lib at 

 http://users.skynet.be/solaris/linuxaudio

(go to the bottom of that page)

It's C++, but you will find some functions in there that
do the setup of both hw and sw params. This is for mmap
access to the device, but you'll find out what to change
or leave out easily. 

(Or you could decide to use the lib of course, but it's
fully undocumented ATM :-(. There is a small example
program that just loops back capture to playback IIRC).
