Synopsis:

#include <sys/asoundlib.h>

int snd_ctl_hw_info( snd_ctl_t *handle, 
                     struct snd_ctl_hw_info *info );

handle: The handle for the control connection to the card. This must be a handle created by snd_ctl_open().
info: A pointer to a snd_ctl_hw_info_t structure in which snd_ctl_hw_info() stores the information.

The snd_ctl_hw_info() function fills the info structure with information about the sound card hardware selected by handle.

Zero on success, or a negative value if an error occurs.
