VBoxSDL.cpp@ 488

Last change on this file since 488 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).
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
