Hello,

I am creating an audio driver under QNX 6.5.

And I have a little problem with HW_CONTEXT_T pointer. 

In my ctrl_init function I've saved *hw_context = my_structure_pointer. And my_structure_pointer, of course, != 0.

But when I receive .aquire PCM callback, first arg (HW_CONTEXT_T*) is NULL.

Am I right that it is not Ok?

What should I do to receive the first arg == my_structure_pointer?

Thanks a lot, I hope that my questions are clear
