Hi, I have a special hardware would like to integrate with FreeBSD. I most probably need to write a driver for it. As I look thru some device driver code, I found this function/macro _IOWR() written in may places of the driver code. Where can I find how does this macro/function defined in FreeBSD? Thanks Sam
