[alsa-devel] what is the difference between SNDRV_PCM_IOCTL_WRITEN_FRAMES and SNDRV_PCM_IOCTL_WRITEI_FRAMES

[Zhang wei]

I know the format likes below when use SNDRV_PCM_IOCTL_WRITEI_FRAMES
<http://lxr.free-electrons.com/ident?i=SNDRV_PCM_IOCTL_WRITEN_FRAMES> 
L+R+L+R+L+R...
L:a frame left channel data.
R:a frame right channel data.
Right?
 
But what is the kind of format when use SNDRV_PCM_IOCTL_WRITEN_FRAMES
<http://lxr.free-electrons.com/ident?i=SNDRV_PCM_IOCTL_WRITEN_FRAMES> ?
 
Thank you:-)
