Subject: C API, usage of function _snd_pcm_file_open()
Date: Thu, 10 Feb 2011 16:49:06 +0100 (CET) [thread overview]
Message-ID: <30083061.18.1297352942734.JavaMail.jon@TT-WS-002> (raw)

I had a look at the Spotify C API, and found that they were using the following code to output music from Spotify: snd_pcm_open(&h, dev, SND_PCM_STREAM_PLAYBACK, 0).
I want use this function instead:
int _snd_pcm_file_open(snd_pcm_t **pcmp, const char *name, snd_config_t *root, snd_config_t *conf, snd_pcm_stream_t stream, int mode)
The function is found here:
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm__file_8c.html#94d0dc725e55a974d792e16f8abdc60a
I'm not able to find anything in the documentation explaining what the two parameters snd_config_t *root and snd_config_t *conf is.
What I'm trying to achieve is to write the stream to a file, and then read it from another application. But it would be even better if I could make the C application write to standard output.
Can anybody help me with this?
I'm not very experienced with either C programming or streaming, but I would really like to make this work.
