Sun Jan 18 17:05:58 1998 Alexandre Julliard <julliard@lrc.epfl.ch> * [include/stackframe.h] [tools/build.c] Some cleanups in stack frame building. * [misc/port.c] Implemented clone() wrapper for libc5 users. * [scheduler/mutex.c] [scheduler/synchro.c] Implemented abandoned mutexes. * [scheduler/process.c] [scheduler/thread.c] We now create a process and a thread structure as soon as possible during initialization. * [scheduler/thread.c] [scheduler/sysdeps.c] Moved system-specific thread handling to sysdeps.c. Fri Jan 16 10:45:15 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [graphics/ddraw.c][include/ddraw.h] Surface handling enhanced. Some stuff already works ;) * [multimedia/dsound.c][include/dsound.h] Implemented using the Open Sound System. Slowly starts to work (sounds terrible for some programs). * [configure.in][multimedia/audio.c][include/config.h.in] Added check for OpenSoundSystem, fixed -lXxf86dga check. Replaced OS #ifdefs by #ifdef HAVE_OSS in mm/audio.c. * [if1632/relay.c][relay32/relay386.c] Do not print control characters for 'str' or 'wstr' args. * [misc/registry.c] "" seems to equals NULL in keynames. Replace where needed. Seems to help the win95 regedit.exe... * [win32/newfns.c] Implemented QueryPerformance* using gettimeofday(2) (should be done using the pentium timers probably). * [tools/ipcl] Removed useless open_pipe construct. Sun Jan 11 17:10:02 1998 Huw D M Davies <h.davies1@physics.oxford.ac.uk> * [objects/region.c] [include/region.h] [graphics/x11drv/clipping.c] Regions are now internal to Wine. The basis of this code is taken from the X11 distribution. GetRegionData() is implemented as is ExtCreateRegion() (without Xforms). CreatePolyPolygonRgn() should behave correctly now. * [objects/metafile.c] [graphics/metafiledrv/graphics.c] [graphics/metafiledrv/init.c] [include/metafile.h] [include/metafiledrv.h] Playback of META_CREATEREGION should now work. Implemented recording of META_CREATEREGION and META_PAINTREGION. * [graphics/x11drv/graphics.c] FillRgn() (and therefore its friends) respect logical co-ords. Wed Jan 7 01:21:45 1998 Steinar Hamre <steinarh@stud.fim.ntnu.no> * [configure.in] [include/acconfig.h] [tools/build.c] Now checking whether to use .string or .ascii. * [configure.in] [include/acconfig.h] [scheduler/critsection.c] Defining union semun if this is not available from header files. * [misc/lstr.c] Moved wine's own header files below <wctype.h> to avoid parse error on Solaris. Sun Jan 4 15:38:07 1998 Andrew Taylor <ataylor@cadvision.com> * [multimedia/mmsystem.c] [multimedia/mmio.c] Implemented mmioSendMessage and rearranged the mmio subsystem in terms of this function. Wed Dec 24 00:51:29 1997 Charles Duffy <cduffy@bigfoot.com> * [windows/clipboard.c] [relay32/user32.spec] GetPriorityClipboardFormat32 now has something other than just a stub. I have no idea if it works (can't test until SetClipboardData is finished) but HEdit likes things a lot more this way.
