question about pointer callback

Hi
I have a (maybe stupid) question about the pointer callback and it's purpose. Is it used for both playback and capture? As I understand it should return the availible data to read (for capture) in number of frames, but should it return the availible space to write to for playback also?

If you mean the pointer callback in a sound card driver module, it
should point to the current possition of the ADC, DAC in the ring
buffer. So it is not "available data to read".
