[ros-kernel] Questions about recent commits to code in User32/Win32k/Gdi

[Thomas Weidenmueller]

my previous post was a bit messy, however i can give you an advice:

write more simple test apps (besides of regression tests) - pass weird 
parameters (e.g. zero or combinations of flags that PSDK claims to be 
incompatible) that you wouldn't expect an application to use and see how 
windows behaves. Change the error code to 0 (SetLastError()) and see 
what error codes are set after the call. Then you can simply figure out 
what windows does in which cases and how it handles errors. I do this 
all the time and so I found many places where wine behaves differently 
in cases of errors.

Thorough testing may help implementing things properly, you can't always 
rely on regression tests.
