Hello everyone, I'm developing a port of a FreeBSD/Linux application that consists of two parts: a kernel and a user land part. The kernel part is build as a WDM driver and is compiled with VS2013 and WDK 8.1: the userspace is going to be compiled under Cygwin for compatibility with user land programs already written for other OSs.
My problem is that the user space program invokes Open(), ioctl(), mmap/munmap(), select() and poll(). I've build a test Win32 app to open with CreateFile the DosDevice with the "\\\\.\\uniioctl" name and everything goes fine, but I've tried to do the same thing with Open(...) with a lot of variants (\\DosDevice\\uniioctl, \dev\uniioctl....) but I'm unable to open the character device. There is some way to do this? For the second main problem, I need to do an mmap/munmap; I was thinking to emulate this mechanism with an IOCTL in the kernel module but doing so, I wouldn't be able to use the mmap provided by Cygwin if I've understood how the things are working; so I'm wondering how to cope with this problem; there's some way to explicitly tell Cygwin where to find the memory that needs to be allocated in userspace? How can I do this in the kernel module?
