Hi, I am doing a project on implementing VFS. Can anyone help me as a mentor? Since I'm more used to in Linux than in ROS code, it would be a great help if someone can help me through. I have gone through the ntos folder and read some documents and also the winvfs project that someone here suggested. I'm aware this is not a prime target in the ROS team, but once I complete this, I might be able to contribute to areas of higher priority. Hoping for a positive reply, Thank you. -- Mahesh M Happy hacking... , , / \ ((__-^^-,-^^-__)) `-_---' `---_-' `--|o` 'o|--' \ ` / ): :( :o_o: "-"

Re: [ros-dev] [ros-diffs] [cgutman] 40142: - Reorganize NDIS code
by Aleksey Bragin 21 Mar '09

21 Mar '09

What was wrong with a previous naming convention? x0gone.c were supposed to contain implementation of functions, which became legacy in that major version of NDIS. Now you substituted it with x0stubs.c, which means it's going to contain stubs only. Was that intentionally?

advapi self forwarding and kernel32 self imports
by Timo Kreuzer 21 Mar '09

21 Mar '09

Hi, 1.) Is there a reason, why some exports of advapi32 are forwarded instead of just set to the proper function? Forwarding is more work for the loader. 2.) kernel32 imports from itself. Which will probably lead to the same result as bug 4292. This is because the mingw lib imports from kernel32 and requires kernel32 library to be added afterwards. But rbuild likes to add mingw lib at the very end of the library list which requires adding kernel32 as a library to mingw_common to resolve imports. This should be fixed and mingw added as the very first library. I wonder if those 2 are even allowed on Windows, as both don't make sense. Timo

Hi All! Good to see it go, I had it in as a safeguard, and now we moved on to the next phase of the rewrite! Thanks Timo!

header hack.... eeh workaround ;)
by Timo Kreuzer 17 Mar '09

17 Mar '09

Hi, I's like to suggest a workaround to the problem that we have to deal with both RECT and RECTL structures in win32k and as they are incompatible need to typecast in a lot of places. RECTL is what the DDI interface uses (almost) exclusively. While the NtGdi Interface and a lot of User structures also use RECT. Both structures are equal, but not compatible when it comes to assigning one to another, So we need to do all these nasty typecasts. My suggestion is adding some defines after the inclusion of windef.h: #define RECT RECTL #define PRECT PRECTL #define LPRECT LPRECTL #define LPCRECT LPCRECTL same for POINT and POINTL I'd like to hear your opinion on that. Thanks, Timo
