Newbie question...

Hi, I have a 3rd party x86 DLL file, that I would like to use under Linux. I have read the documentation on the specmaker tool, which would seem to provide some help. The thing that makes my case a bit different is that I would like to use the DLL within a Linux native program, not a WineLib program (its just a command line application and I need it to be very lightweight). Im pretty sure the Wine code can help me out, but Im not sure what the easiest way to proceed is, and what parts I need to use. Thanks in advance, -elan

T@x2001: Linuxport via Wine
by Joerg Mayer April 4, 2001

April 4, 2001

Just found the following at the SuSE portal pages (German only): http://portal.suse.de/de/content/reports/tax2001.html Rough translation on the introductory paragraph: The program t(a)x by Buhl Data has been around for the Windows platform for some years. This year, the current version T(a)x2001 has been made available for the Linux OS for a first time. In order to do this the Windows emulator Wine was used. Wine allows using Windows applications running Linux. This emulator has been modified to work with t(a)x2001. The summary as far as Wine is concerned: The program should be more stable and faster. Does anyone know which modifications were made to wine? Ciao Jörg -- Joerg Mayer <jmayer(a)loplof.de> I found out that "pro" means "instead of" (as in proconsul). Now I know what proactive means.

Yes, in the Wine debugger, which should store the name and simply continue execution, just like the MSVC debugger does. -- Alexandre Julliard julliard(a)winehq.com

Re: Speeding up wineserver syncronization objects with shared memory
by David Howells April 3, 2001

April 3, 2001

Okay, I've thought about how to make the wine kernel module easier to use for Wine, and I've started adding another API to it - one that interprets Wine server messages. When I designed the module initially, I decided to make it possible to add as many API's as I liked, so in theory it's not too difficult. I'm currently performing a major rearrangement of the files that comprise the module: * Splitting the current win32 API bits out of the same files that contain the actual object class implementations. * Putting the core and the API's in separate subdirectories. * Abstracting name support, so that the internal API takes an "object name" which the user API is responsible for extracting from userspace and converting from WCS/MBS as necessary. * Fixing introduced bugs. This does not mean that I'm getting rid of the Win32 API I've already got! It will just be optional. Calling the new API will be by means of either: union generic_request msg; syscall(__NR_win32,WINESERVER_WINE_SERVER_MESSAGE,&msg); Or: union generic_request msg; int fd = open("/proc/wineserver"); struct WineserverIoctl wioc = { WINESERVER_WINE_SERVER_MESSAGE, &msg }; ioctl(fd,WINESERVER_IOCTL,&wioc); David

Interesting Magic # exception understood by the MS debugger...
by James Hatheway April 2, 2001

April 2, 2001

Hi guys, I encountered something interesting while debugging a newer build of my application. I noticed that all of a sudden I was receiving approximately 10 new exceptions in the debugger on startup that I wasn't receiving before. After digging a little, I found out that the app coders were making use of a 'hidden' feature of MS VC that allowed you to name your threads (thus allowing for easier debugging). To do this, you call RaiseException with the code of 0x406D1388. (Search on deja.com or google.com for "0x406D1388" for details.) The windows debugger seems to be on the lookout for this code. Of course, what it does in wine is just breaking into the debugger many times and getting on my nerves. :-) For now, I put the little hack I attached to this mail in my tree to save my sanity. My question to the list is, (A) is there a way to name threads in Linux/Unix (I don't think so, but of course I could be wrong) and (B) should we support MS's hack somehow in the official tree? -James -- James Hatheway Software Designer - Macadamian Technologies, Inc. james(a)macadamian.com ~ http://www.macadamian.com "Man könnte froh sein, wenn die Luft so rein wäre wie das Bier" "One could be happy if the air were as pure as the beer"

Ah, I didn't know Regedit was not giving the true value. That complicates matters even more. It seems I'll have to do some experiments. -- Dave Pickles

I don't see how you can get the right semantics this way, but maybe I missed something. How will you be able to wake a single thread for auto-reset events, but all of them for manual events? How are you going to implement PulseEvent? How can you do WaitForMultipleObjects for an auto-reset event without a race? -- Alexandre Julliard julliard(a)winehq.com

event flags using pipes
by Mike McCormack April 1, 2001

April 1, 2001

Hi, i've written an implementation of windows event flags using pipes. (The modifications are confined to server/event.c for the moment.) Why? By changing the client side implementation of SetEvent and ResetEvent the use file descriptors and implementing a client side unix fd/handle cache, it should be possible to eliminate server calls for these operations and improve the performance of wineserver. Anyway, any comments are welcome.

RegSetValueEx problem?
by davep March 31, 2001

March 31, 2001

I've been trying to track down why WineMine does not save my best scores ;-( On exit, WineMine saves the current user settings to the registry with code like this: char data[16]; wsprintf( data, "%d", p_board->pos.x ); RegSetValueEx( hkey, "Xpos", 0, REG_SZ, (LPBYTE) data, sizeof( data )); The problem here is that the 'count' parameter passed to RegSetValueEx is not the string length but the size of the entire buffer. Wine dutifully writes into the registry the entire buffer including the trailing garbage, and also adds a null to the end if there isn't one there. When WineMine tries to read the value back it is now 17 characters long and too big to fit in the 16-byte buffer. Compiling and running Winemine under Windows 95 this problem doesn't occur. Win95 truncates the value at the first null. So RegSetValueEx needs fixing. However there are already comments in there about the differences between 95 and NT in the handling of REG_SZ values, and I don't have an NT system to carry out checks. Can someone with experience propose a solution? -- Dave Pickles
