VirtualBox

source: vbox/trunk/src/VBox/Main/include/FramebufferImpl.h@ 2333

Last change on this file since 2333 was 470, checked in by vboxsync, 18 years ago

Main/Frontends: Changed all interface attributes and method parameters that used to use ULONG to pass pointers around; they now use BYTE * for this purpose (should fix problems for 64-bit targets).
