This device uses /dev/dsp write and ioctl to do what I want. I would now like to move this to the driver that creates the audio data. Right now I have to open both devices and transfer the data via user space between the two devices. How do I open and use ioctl from another driver? I know about the ksyms but have not been able to understand the move from opening a file pointer and using ioctls in user space to directly connecting two drives using the kernels symbol table (ksyms). Thanks, J. Deas
