GrayDBufSetActiveIdx |
Function (Macro) |
Sets the currently visible double buffer.
GrayDBufSetActiveIdx sets the currently visible buffer to the one indexed by
idx, which should be either 0 or 1. Afterwards,
GrayDBufGetActiveIdx will return
idx, and
GrayDBufGetHiddenIdx will return
the opposite. As the switch may happen during the time a plane is copied to
the screen, it may be desirable to use
GrayDBufSetActiveIdxSync
instead.
