I perhaps worded my original mail badly. The code is the same only as far as I used the same function and variable names (but s/serial/parallel/). The actual functions themselves have some significant differences. Putting conditions all over the serial stuff doesn't seem the most elegant way of implementing this. But if that's what it will take to get my patch accepted then I'll get onto it.

Question regarding development..
by Jon Brandenburg 07 Sep '03

07 Sep '03

Hi, I've read many of the various articles/faq's etc posted on the winehq.com website, but I have not encountered any so far the really answer my question. My question is this, I have a Universal Subscription to MSDN which includes among other things, debug versions of the operating systems. Am I allowed to run debug os in connection with say a piece of test code, with the purpose of extracting the necessary api information/functionality so it can be rewritten into wine or must I treat it as a black box and ignore the debug versions that I possess? If my question isn't clear enough I'd be happy to restate it. Thanks! Jon PS: I did just have the idea to actually check the license included with the debug os version to see what if anything that it states.. hmm lets see...

Papers on legal aspects of reverse engineering
by Dan Kegel 07 Sep '03

Somebody was asking about what is allowed with respect to using Microsoft SDKs when writing Wine code. I have no answer for his question, but did spend a few minutes digging up interesting bookmarks on reverse engineering in general. Maybe they'll be of some interest. http://reengineer.org/ http://www.chillingeffects.org/reverse/faq.cgi http://www.digital-law-online.com/lpdi1.0/treatise25.html http://www.digital-law-online.com/lpdi1.0/treatise48.html http://www.sims.berkeley.edu/~pam/papers/l&e%20reveng5.pdf http://www.law.cornell.edu/commentary/intelpro/chn95int.htm http://www.lawplusplus.com/column10.htm http://www.lgu.com/publications/softcopy/12.shtml http://research.sun.com/people/cristina/legal-computing-publications.html - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Porting radio driver from MS to Linux
by Arjen Verweij 07 Sep '03

07 Sep '03

Hi, I am looking to port a MSVC++ driver to Linux. The recommended approach, to convert the Makefile and compile it didn't work for me, so I am trying to compile seperate cpp.files by implementing the winapi functions I need in a seperate linuxapi.cpp There are about 30 functions I have to port at the moment, and some of them are easier than others. Basically they are part of the DLL (so), thread/event/mutex, File*Find apis, with some miscellaneous ones. I think I could do myself a favor by asking if the MSVC++ code could use libpthread instead of the MS threads, so I'm not too worried about those, and simulating DLL with the dl* api seems easy enough as well. Still, there are problems with Find*File, FindClose, GetModuleFileName and so on. I'm not too familiar with winapi myself, because I learn C/C++ in a college environment, where most programming assignments are geared towards Linux. Can anyone comment sensibly on this? If you are of the opinion that I should just rewrite the app from scratch, I agree in part, but the assignment is to leave as much of the original code as it is, apart from isolated cases where g++ can't quite follow the MSVC++ compiler. At the end of the email is a list of prototypes included, that I ripped from winbase.h Looking forward to read your thoughts on this matter, Regards, Arjen Verweij Here is the list: DWORD GetModuleFileName(HMODULE, LPTSTR, DWORD); HANDLE FindFirstFile(LPCSTR lpFileName, LPWIN32_FIND_DATA lpFindFileData); BOOL FindNextFile(HANDLE hFindFile, LPWIN32_FIND_DATA lpFindFileData); BOOL FindClose(HANDLE hFindFile); BOOL SetEvent(HANDLE hEvent); FARPROC GetProcAddress(HMODULE hModule, LPCSTR lpProcName); HMODULE LoadLibrary(LPCSTR lpLibFileName); BOOL FreeLibrary(HMODULE hLibModule); HANDLE CreateMutex(LPSECURITY_ATTRIBUTES lpMutexAttributes, BOOL bInitialOwner, LPCSTR lpName); DWORD WaitForMultipleObjects(DWORD nCount, CONST HANDLE *lpHandles, BOOL bWaitAll, DWORD dwMilliseconds); BOOL CloseHandle(HANDLE hObject); BOOL ReleaseMutex(HANDLE hMutex); DWORD GetCurrentProcessId(VOID); HANDLE CreateEvent(LPSECURITY_ATTRIBUTES lpEventAttributes, BOOL bManualReset, BOOL bInitialState, LPCSTR lpName); VOID Sleep(DWORD dwMilliseconds); BOOL ResetEvent(HANDLE hEvent); DWORD _beginthread(void(__cdecl *start_address) (void*), unsigned, void*); VOID OutputDebugString(LPCSTR lpOutputString); DWORD WaitForSingleObject(HANDLE hHandle, DWORD dwMilliseconds); void _endthread(void); BOOL ReleaseSemaphore(HANDLE hSemaphore, LONG lReleaseCount, LPLONG lpPreviousCount); HANDLE CreateSemaphore(LPSECURITY_ATTRIBUTES lpSemaphoreAttributes, LONG lInitialCount, LONG lMaximumCount, LPCSTR lpName); BOOL UnmapViewOfFile(LPCVOID lpBaseAddress); HANDLE CreateFileMapping(HANDLE hFile, LPSECURITY_ATTRIBUTES lpFileMappingAttributes, DWORD flProtect, DWORD dwMaximumSizeHigh, DWORD dwMaximumSizeLow, LPCSTR lpName); DWORD GetLastError(VOID); LPVOID MapViewOfFile(HANDLE hFileMappingObject, DWORD dwDesiredAccess, DWORD dwFileOffsetHigh, DWORD dwFileOffsetLow, DWORD dwNumberOfBytesToMap);

Dynamically altering drive mappings at runtime
by Mike Hearn 07 Sep '03

07 Sep '03

.... and on a slightly related note, I am wondering how hard it would be to allow wine to alter drive mappings at runtime. The reason I ask is that it'd be nice for the "add drive" dialog in winecfg to use the shell directory chooser that shows all directories on the system rather than forcing the user to type in a path manually, which is error prone. To do that, of course we need a few things: * the ability to map / if it's not already mapped (or maybe we should just force / to always be mapped to drive Z in the wine code) * the ability to switch off drive letters showing through in the directory chooser dialog, so it's less confusing to see this magic letter appear. Thoughts on how hard this is? thanks -mike

Using fontconfig
by Mike Hearn 07 Sep '03

07 Sep '03

Hi to anybody who knows about fonts, It'd be nice to use fontconfig in future to locate font installation paths. There is a simple API: FcStrList FcConfigGetFontDirs (FcConfig *config); which should let us use a small part of it, even if we don't use all of it. It means we don't need to make the user manually configure font paths. Does anybody know how hard this would be? thanks -mike

Problems with libartsc.so
by jeff_latimer 07 Sep '03

07 Sep '03

I have just upgraded to RedHat 9 and when I make wine it can't link in libartsc.so . Looking in /usr/lib there is a libartsc.so.0 not libartsc.so . Is this normal? Jeff ---------------- Powered by telstra.com
