CryptoAPI
by Travis Michielsen 04 Sep '01

04 Sep '01

Hi, I was going to start implementing the Cypto API (in advapi32.dll) over the next few weeks. As of yet these functions are no more than stubs. However, I am finding increased use of this API as more applications becomed networkable and relying more heavily on internet connections. I was hoping to implement these functions by using the OpenSSL library (if/when available). This library seems to have similar capabilities. One of my concerns is about legal issues. What special concerns should I note about cryptographic software? Are there any special copyright issues I should be aware of? Another question is about design. M$ seems to split the cryptographic software into different dlls (rsabase.dll, rsasig.dll, dssbase.dll, etc.). Should I do this as well so that, applications can use the native dlls if necessary or should I simply implement it entirely though advapi32.dll which and avoid the need to create several new (and very small) dlls under wine? Because most of the code is already in another library (OpenSSL) creating extra dlls seems abit unnecessary. - Travis _________________________________________________________ Do You Yahoo!?

Re: wine-devel digest, Vol 1 #445 - 9 msgs

Attempt 2 :-) I am trying to get winsock to work under Solaris and need a little help. When connecting, the call to connect doesn't generate a syn packet as expected, The problem appears to be WSOCK32_socket, where the type of socket is passed as type 1 for a tcp service, as it turns out the Solaris header file defines SOCK_STREAM as 2 and SOCK_DGRAM as 1 which makes the subsequent call to connect succeed without establishing a connection because a UDP endpoint was created instead of a tcp one. Now to find out where SOCK_STREAM is getting defined as 1 :-/ I probably need to check the standard function calls between a solaris binary and a windows one so does someone have a simple test program and a unix source (IE windows binary with unix compatible source code) that I can use to compare behaviours between the two environments ? Thanks Bob

Problems with WM_PAINT and threads

After trying to merge Wine 20010824 into WineX, I've encountered a threading issue.

As no win function is uses, you can easily write a test programm wrapper, like static char *_ultoa(... void main() { char buffer[32]; printf(" x %d, radix %d, result %s\n",1000,10,_ultoa(1000,buffer,10)); printf("... } The loop decrements p after use, so p needs to be corrected and I would think that the original version is right.

Mouse Events
by Brad Campbell 30 Aug '01

30 Aug '01

G'day all, Maiden post. Please be gentle.. I had a problem using wine with a touchscreen under XFree 4.0.2. With the help of Gerard Patel and Ove Kaaven I have come up with a patch that solves my problem, and does not appear to disrupt any of the other machines and programs I use. I have looked at several ways of achieving this, and this seems to be the least messy. This has been tested with both the touchscreen and also ps/2 mouse and works well with both. I'm not a C programmer at all, and have little experience with the WINE code. All comments both positive and negative appreciated.. Thanks..

Comment from IBM developer re FS register corruption
by Jeremy White 30 Aug '01

30 Aug '01

At LinuxWorld today, a couple of developers from IBM stopped by and mentioned a patch that they recently sent to Linus (which he accepted with dismay at such a long standing bug, and apparently committed to the 2.4.8 tree). Sadly, I have forgotten the woman's name, but she indicated that there was a race condition that could sometimes cause the fs register to become corrupt, and that this problem had existing in all versions of Linux, as far as they could tell. She indicated that the patch had a fairly innocuous description, but it might be worth understanding this problem better (although from her description, it didn't sound like a good workaround was available). Cheers, Jeremy p.s. Wine was a finalist for best open source project, but lost out to KDE. Next time, the crystal plaque is ours. I can feel it.

Powerdvd running under linux
by Robert Lowery 30 Aug '01

30 Aug '01

Hi I have a graphics card with an SIS6326 chipset. Under Windows 98 (using PowerDVD), I get fantastic performance on my Pention 233MMX as it supports YUV->RGB, Motion Compensation and iDCT in hardware. This chipset is not currently supported under Linux. What do you think the chances are of PowerDVD working with hardware acceleration under WINE/WINEX? What sort of performance should I expect? Please cc replies to my email, as I am not subscribed Thank-you for your help -Robert

./configure file in cvs
by Gioele Barabucci 29 Aug '01

29 Aug '01

Hello everyone, why is there a ./configure file in your cvs? configure was meant to be created for endusers, not for developers. Many projects based on auto* tools create a ./autogen.sh or ./bootstrap script. The fact is that the configure supplied (and all the auto* files) creates lot of confusion and some errors sometime. simple as: #!/bin/sh # rm -f configure ltmain.sh config.guess config.sub echo "Running libtoolize..." libtoolize --force --copy >/dev/null echo "Running aclocal..." aclocal $ACLOCAL_FLAGS echo "Running autoheader..." $use_autoheader echo "Running autoconf..." $use_autoconf echo "Running automake..." automake --add-missing --copy --foreign -- Gioele Barabucci (Gb]) <gioeleb(a)tiscalinet.it>
