VirtualBox

source: vbox/trunk/src/VBox/Additions/x11/vboxvideo/vboxvideo.c@ 69075

Last change on this file since 69075 was 69075, checked in by vboxsync, 7 years ago

Additions/x11/vboxvideo: Several small clean-ups.
bugref:9017: Additions/x11: put vboxvideo into upstream X.Org

This change:

  • Removes a forgotten unneeded dependency.
  • Corrects the usage of quote and angular brackets with X.Org and X11

header files.

  • Removes an out-dated comment.
  • Removes the BOOL_STR macro which was only used in one place.
  • Removes the unneeded initialisation of the guest library, which is no

longer used in the driver at all.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
