Can you help me with an SHM related problem?
I'm currently writing a Win32 emulation kernel module to help speed Wine up, and I'm writing the file mapping support stuff at the moment (CreateFileMapping and MapViewOfFile).
I have PE Image mapping just about working (fixups, misaligned file sections and all), but I'm trying to think of a good way of doing anonymous shared mappings without having to hack the main kernel around too much (so far I've only had to add to kernel/ksyms.c).
Is there a reasonable way I could hook into the SHM system to "reserve" a chunk of shared memory of a particular size, and then a second hook by which I can "map" _part_ of that into a process's address space?
Cheers, David
