Hi, Just incase anybody is interested, here is a regression test for mailslots. There's not much point to include it into Wine until we support mailslots properly (which I'm working on).

Why not include it as a todo_wine{} in the tree? (if you are far away with your mailslot impl, if not, I guess it can wait for it). -- Dimi.

I have some code for the mailslot implementation, but it's weekend work for me. It would be pretty easy to wrap the test in a todo_wine{} but we already know that none of the tests will pass, so it won't prove much. I think I'll just wait until I have an implementation that works. I've run my test on WinNT 4... if somebody felt like verifying it on Windows 2000 and Windows XP, that could be helpful. Mike

Seems like a good reason to put the tests in Wine: it makes it more likely that people will run them on Windows 2000, Windows XP, Windows 95 (does it even support mailslots?), etc. -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ War doesn't determine who's right. War determines who's left.

Which would be easier if the test was submitted to Wine. Jakob
