Hexdumping function?
by Benjamin Cutler 16 Apr '05

16 Apr '05

I'm writing a conformance test for my implementation of powrprof.dll that I've been working on, and something I'd like to do in the test is dump the contents of some structs to the screen without trying to make it pretty. I cobbled together the following function, but I'd like to know if there's something like this already so I don't reinvent the wheel: void hexdump(void *p, int len) { int i; long *src = (long *)p; len /= 4; for(i = 0; i < len; i++) { printf("%08lX", src[i]); } }

Exception in wcstombs_sbcs

Hi, when I run the latest Process Explorer (Version 9.0.3) I sometimes get an exception: fixme:ntdll:NtQuerySymbolicLinkObject (0x777e2ce4,0x777ebc28,0x12e4f878) stub wine: Unhandled exception (thread 000b), starting debugger...

Re: advapi32 registry test, fail gracefully when no permissions

As the test stands now, it doesn't pass on any windows machines because you have to manually set the backup and restore privileges. The patch I have sets these permissions then unsets them after the tests are run. -- James Hawkins

TrashCan Day 3 - Use FreeDesktop TrashCan
by Steven Edwards 15 Apr '05

15 Apr '05

Hi, Yes I know this does not look that nice atm. Its still a work in progress but you get the idea of where I am going with it. With this patch any SHFileOperation with the FOF_ALLOWUNDO flag will move files to the users ~/.Trash. There is a draft spec on www.freedesktop.org on how the Trash is supposed to work but currently KDE does something totally different and GNOME is not compliant so I am not sure how I am going to deal with that yet.

There's not much I can say in the way of development, but as a user, getting USB support (beyond what's supported in the kernel) would be a HUGE leap of improvement for Wine. I think others have said before that there are a lot of apps out there that will run on Wine, but are useless because they depend on their hardware counterpart. (In the music world, Guitarport comes to mind.) Hiji __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

script for quickly finding large functions
by Joris Huizer 15 Apr '05

15 Apr '05

Hello, I made this script to find large functions; I think it may be usefull to add at the janitorial page where the note on large functions was placed; It assumes no things are between functions, so it gives some incorrect matches; also, it accidentilly reads some if() and switch() statements, but in some (most) cases those are actually in large functions if they show up high. I hope this is usefull, it did find some interesting large functions like HRESULT WINAPI IDirectMusicContainerImpl_IPersistStream_Load (dlls/dmloader/container.c) which has like 7 levels of nested switch statements regards, Joris BEGIN {line_no = 0; file="";} { if ($1 != file) { if (line_no != 0 && index(file,".c") != 0) { printf("?: %s %s\n",file,var); } line_no = 0; file = $1 } if (line_no != 0 && index(file,".c") != 0) { printf("%6d: %s %s\n",($2 - line_no),file,var); } line_no = $2 var = ""; for (i = 3; i <= NF; i++) { var = sprintf("%s%s ",var,$i); } }
