Hi.
While doing some Regression-Testing for wine ("http://www.winehq.org";),
I run into some Problems with qemu and win95/win98 as guest.
When calling GetPrinterDriverDirectoryA with bad/incomplete Parameter,
GetLastError() returns "0" (ERROR_SUCCESS) on qemu with win95 or win98
as guest, while vmware/win98 or native/win98 returns
"87" (ERROR_INVALID_PARAMETER).
Example:
winspool.drv:info on http://test.winehq.org/data/200511161000/#Win98
host:
Ubuntu linux 5.04 (Kernel: 2.6.10)
qemu: 0.7.2 and cvs-snapshot 2005-11-20
guest:
win98se (german)
win95c (german)
I stripped the failing Tests down to a short App.
(Source attached, binary available on request)
Different compilers where used:
i686-mingw32msvc-gcc (GCC) 3.3.3 (other linux system)
i586-mingw32msvc-gcc 3.4.2 (on my linux)
For the short Test-App, i used the Pelles C-Compiler:
pocc 3.00.10 (with wine on my linux)
Any Ideas how to fix this?
(More Problems with qemu exists, but for me, the bug above is important)
