Failure running 1998-era online manual
by Dan Kegel 07 Dec '02

07 Dec '02

I grabbed Wine-20021125 and built it on my Red Hat 7.3 box. Its behavior installing http://enduser:enduser@bbs.toshiba.co.uk/file/area128/S22D95UM.ZIP (the Windows 95 version of the user manual for my 1998-era Toshiba laptop) seems much improved over May/June 2002 wine, cool! However, running the app does no better. To run the app, you do cd 'c/Program Files/DOC' wine edoc32.exe TOSHIBA.M14 On Windows, it works fine. On Wine, it displays a splash screen, then exits. Here's a partial … [View More]

Where to use dosdev
by György 'Nog' Jeney 07 Dec '02

07 Dec '02

In some of the int21 routines it says that we should use DOSDEV_Peek/Read/Write. Should we also use the functions in the devices.c to implement all functions on devices like ioctls etc.? nog.

small updates to debugger.sgml
by Tony Lambregts 07 Dec '02

07 Dec '02

Before I could feel right about adding "Advanced Debugging Techniques" to the documnetation I needed to update the documentation on the debugger. There is still one section that is out of date (that I am aware of). The section that I am refering to is as follows > Program hangs, nothing happens > > Switch to UNIX shell, get the process-ID using ps -a | grep wine, and > do a kill -HUP <pid> (without the < and >).

I have added a fix me message in front of this since I am unable to come up with anything usefull to replace it. If anyone has a usefull suggestion I would appreciate it.

Janitorial Projects
by Dimitrie O. Paun 06 Dec '02

06 Dec '02

Folks, I have updated the Janitorial section: http://www.dssd.ca/wine/Wine-Fun.html#janitorial with the list of cross calls from 32->16, and W->A. There are currently 13 cross calls from 32->16 bit code, and 194 cross calls from Unicode to ASCII. Any takers? :) -- Dimi. P.S. If you do work on some of those, let me know so I can put your name there, and mark what's being worked on, do we can avoid duplicated effort.

how to switch between threads
by Rajesh Akkineni 06 Dec '02

06 Dec '02

Hi, I am debugging wine with MS Media Player. Some places the program is blocking with som 7 to 8 threads opened. They are all waiting for a some event(ConnectNamedPipe) But i think there should be another thread with will Create the file or NamedPipe. So How can i see where the other threads are when i set a break point in a perticular method. How dose debuggers handle MultiThreaded Applications? Can i Shit to different Thread to exmine where is it when the program Halted? Thanks Rajesh … [View More]

valgrind and wine
by Dan Kegel 05 Dec '02

05 Dec '02

valgrind wine reports: ==6476== Valgrind detected that your program requires ==6476== the following unimplemented functionality: ==6476== modify_ldt(): I (JRS) haven't investigated this yet; sorry. ==6476== This may be because the functionality is hard to implement, ==6476== or because no reasonable program would behave this way, ==6476== or because nobody has yet needed it. In any case, let me know ==6476== (jseward(a)acm.org) and/or try to work around the problem, if you can. Dang. - Dan
