wine/dlls/winegstreamer/h264_decoder.c
Kurt Kartaltepe 18e79f813b winegstreamer: Replace pointers with handles in PE->Unix transition. 
Converts struct pointers in syscalls to 64bit opaque handles. This makes future wow64 thunking
simpler and should avoid dereferencing Unix pointers in the PE code.
