Hi Takashi,

For alsa pcm we have two ways to write data, either we use write()
system call or use ioctl SNDRV_PCM_IOCTL_WRITEI_FRAMES.

Is there any specific reason why we have two methods and which one is
preferred and why?

This question is basically for compress API, should we add similar write
method thru ioctls, if so why?
