These are here to support compilers that don't have gcc-style inline assembly. This is admittedly a theoretical issue at this point, but there shouldn't be any harm in keeping them around just in case. -- Alexandre Julliard julliard(a)winehq.com

I think that the result should be assigned to the output parameter. Yes of course, stupid typo on my part. Thanks for spotting it. -- Alexandre Julliard julliard(a)winehq.com

Some strange code in configure.in

by Lionel Ulmer

Hi all, By looking at some guy's config.log, I found out this in configure.in : dnl Check for GLU32 library. AC_CHECK_LIB(GLU,glBegin, X_PRE_LIBS="$X_PRE_LIBS -lGLU" GLU32FILES='$(GLU32FILES)' GLU32_DLL=glu32 ,, $X_LIBS $X_PRE_LIBS -lXext -lX11 -lm $X_EXTRA_LIBS ) My question is why do we test for 'glBegin' in GLU and not something better like, say, 'gluLookAt' ?

If you look at the source of Escape16 you will find this: case GETPHYSPAGESIZE: case GETPRINTINGOFFSET: case GETSCALINGFACTOR: { POINT16 *ptr = MapSL(in_data); POINT pt32; ret = Escape( hdc, escape, 0, NULL, &pt32 ); ptr->x = pt32.x; ptr->y = pt32.y; return ret; } The function is called like this: 0806c1c8:Call GDI.38: ESCAPE(0x0000,0x000d,0x0000,0x00000000,0657:e8f4) ret=0ff7:4428 ds=1207 The in_data pointer is null but the code assigns to it, thats why it crashes. I think that the result should be assigned to the output parameter. Ladislav Sladecek

The static table is OK, but you'll need to add a number of functions that were done by escapes before (AbortDoc, StartDoc, etc.) And of course there is still the GDI lock issue so I don't know if you can actually print something even if you fix the initialisation. -- Alexandre Julliard julliard(a)winehq.com

It shouldn't be > too hard to fix, but I haven't had time yet. Volunteers are welcome... I continued with my experimets. 1) The application _is_ braindead; Andreas Mohr is right. The application has tried to open the ,, driver always, even before the July 26th when the crashes started. This is harmless by itself. On 27th, Alexandre Julliard just added an error message to the CreateDC. - if (!(funcs = DRIVER_FindDriver( buf ))) return 0; + if (!(funcs = DRIVER_load_driver( buf ))) + { + ERR( "no driver found for %s\n", buf ); + return 0; + } The error message confused me as it has not been there before. 2) The real reason for the crash is that the application calls Escape16 with hdc equal to 0 and function equal to GETPRINTINGOFFSET. I do not understand why, they did not even start to print. Maybe, this is an undocumented windows function? After I temporarily disabled Escape16, the application began to work. 3) Now, the CS_PARENTDC, WS_CLIPSIBLINGS fix works fine for me, thank you. 4) To fix Escape16, the 16bit printer driver is necessary. I need printing either. I will try to work on it if you just give me a piece of advice. I think that two ways are possible: A) To use the static table and to modify create_driver to work with it. B] To create a 16bit printer driver DLL similarly to the 32bit drivers. Whis one is better? Ladislav Sladecek

Implementing Winsock2 Function

by Nick Bauer

Hello, I was working with Andreas Mohr on a program I was trying to get running under Wine, and he suggested that I email this list and ask for help to get an un-implemented function implemented. My application is a software program used to control our phone system. The error is: Unhandled exception: unimplemented function ws2_32.WSALookupServiceBeginA called in 32-bit code (0x407be056). In 32-bit mode. 0x407be056 (__wine_unimplemented+0x56 [ws2_32.spec.c:40] in WS2_32.DLL): jmp 0x407be050 (__wine_unimplemented+0x50 [ws2_32.spec.c:40] in WS2_32.DLL) 43 void __wine_stub_ws2_32_WPUCompleteOverlappedRequest(void) { __wine_unimplemented("WPUCompleteOverlappedRequest"); } I have tried using the native WS2_32 DLL and then the program no longer crashes, but it looks like its attempting to connect to the server, but never gets connected. I set up iptables to log all packets going to that server out eth0, but it never catches any packets. Any help would be greatly appreciated, as I have no knowledge of coding. Also, I am not on the list, so please include my email on any responses. Thanks a lot, -Nick
