Can someone help me get through the wineserver code for passing data
through a buffer in response to an ioctl?
Our (slightly out of date 1.3.24 version of) Wine is getting
INVALID_HANDLE_VALUE returned for FindFirstVolume. The problem is that
the FindNextVolume call inside FindFirstVolume fails because it is told
there are no mount points.
I have tracked the code through FindFirstVolume through
NtDeviceIoControlFile to server_ioctl_file on the app side.
On the wineserver side I can see the wineserver fielding the ioctl
request, and mountmgr.sys filling a buffer with 5 mount points.
But this information is being written into a buffer (address 0x12510) by
the wineserver that is not making it back to FindNextVolume buffer
(address 0x29820) on the app side.
Where do these buffers come from? Do they use shared memory? Or is the
info passed through a pipe? I'm having trouble making my way through the
wineserver code, so any tips or pointers would be appreciated!
