Linux driver development

[asankaan]

Hi,
I'm developing a Linux driver for a PCI interfacing card. I'm using /proc interface as my communication point for the driver.(read_proc and write_proc functions for reading and writing). I wnat to pass a pointer from usrspace to the driver. How can I do it? Is ther any way similar to IOCTL handles in proc system?

Thanks.
Anyhow I switched to file operation structure with IOCTL operations. It was very easier than /proc.
