Where is snd_pcm_writei() defined?
 

I am writing a small demo code that opens a audio device on my board and play a sound on the speaker.

I have the aplay.c as sample code. In it it calls snd_pcm_writei(), but I cannot find this being defined anywhere in the source tree.

I am running 2.6.19 on a ARM board.

Thanks

Look inside the sources of the ALSA library.

Can I not use the ALSA library and write directly to the /dev/snd/pcm... device to emit a sound from the speakers?

Any sample code will greatly help....

Thanks
