Descrepancy between Windows and GLIBC version of [v]snprintf
by Daniel Gehriger Nov. 26, 2003

Nov. 26, 2003

Hi, I found a problem with the _snprintf() / _vsnprintf() functions. Wine seems to use the forward these function calls to their native implementation (eg. in GLIBC). The problem is that they behave differently under Windows and GLIBC: Both function take a parameter to specify the maximum number of characters to write. Under Windows, if the formated string is equal in length to or exceeds the specified number, the terminating NULL will NOT be written to the buffer. Under Linux, the terminating NULL is ALWAYS written. The test program below produces the following output (only when linked dynamically, of course) : Under Windows: 0000000001**** Under Wine: 000000000 When compiled on Linux: 000000000 --------------------------------------------------------- #include <stdio.h> #include <memory.h> int main() { char buffer[16]; memset(buffer, 0, 16); memset(buffer, '*', 15); int len = _snprintf(buffer, 10, "%010d", 1); printf("%d : %s\n", len, buffer); return 0; } --------------------------------------------------------- Regards, Daniel

PRIVATE flag sends dllwrap for a loop.
by Steven Edwards Nov. 26, 2003

Nov. 26, 2003

Hello, This is a problem I have had for a while building WINE dlls for use on Windows and ReactOS. When linking the dlls dllwrap always complains that it cant find the symbol private that is added to the .def file. When I remove this symbol and rebuild my import libs and dlls I dont have any problems so lets disable it for now. Changelog: Disable PRIVATE name on for exports in def files.

Re: netapi32: implement Netbios()

Nov. 26, 2003

Hi Uwe et al.. Uwe said: > Saying a little more may help. > > What's needed to test you patch? What programs show > improvement? Good questions. I have little test programs that I've been using, but NetBIOS is hard to test without knowing something about your network configuration, so they're not much use for netapi32/tests. I don't know of any programs that work now that didn't, except what I'm working on: I'm trying to implement the Network Neighborhood. I've been tweaking WINE's SMB code to use Netbios() rather than implementing the netbios-over-tcpip stuff directly. That work isn't done yet, watch this space for more :) There was an article a while back linked here about some HP management program (for their NAS appliance) that didn't discover their box under WINE because of lack of NetBIOS support. I suspect this may now work, but I don't know. > Any configuration items needed in a .ini file or the > registry? Needed? No, should work as-is. You may configure some things in the registry if you need to. Many are configured in the same way as Win98's reg, but not all. I didn't know a good place to document these; comments in winedefault.reg??? > And thanks for your work :-) You're very welcome :) --Juan __________________________________ Do you Yahoo!?

PE stack trick not working on lowmem machines
by Marcus Meissner Nov. 26, 2003

Nov. 26, 2003

Hi, On SuSE 8.2, i586 glibc, loader/wine-* crash due to the 256 MB static array in main(). The test machine has just 64MB RAM and 200MB swap. If I start decreasing the array it works, up to 201MB. $ /lib/ld-linux.so.2 ./wine-kthread ./wine-kthread: error while loading shared libraries: ./wine-kthread: cannot map zero-fill pages: Cannot allocate memory $ So ld.so really wants to get 20xMB memory but fails. -> Not good on low memory machines. (Not sure if we should fix it.) Btw, why don't we use -Wa,--noexecstack ? Ciao, Marcus

I would actually agree with Alexandre here, but W2K at least behaves differently. My tests show that RemoveDirectory just as CreateDirectory rejects all paths which contain one of the wildcards ": * ? \" < > |" with error 123 completely independent where that character occurs (not just in the path element which is created). And as far as I can say DeleteFile just as much behaves also this way. So should we attempt to be smarter than Windows in this case? Rolf Kalbermatter
