NAME

       ggiGetRayPos - Find out where the raster beam is

SYNOPSIS

       #include <ggi/misc.h>

       int ggiGetRayPos(ggi_visual_t vis, int32_t* x, int32_t* y);

DESCRIPTION

       Though  currently  only  implemented via matroxfb, this function will retrieve the current
       position of the raster beam on a display that uses a cathode ray tube, or  resembles  such
       internally.  Because it has not been implemented and put into widespread use, there may be
       API fluctuation as to exactly what units  x,  y  are  in,  especially  on  displays  using
       doublescanning  modes.   In  addition  to  numerical  values,  the following values can be
       returned in either dimension: GGI_RP_BORDER means the raster  is  in  the  border  of  the
       screen;  GGI_RP_BLANK  means  the raster is past the border and is turned off; GGI_RP_SYNC
       means the raster is retracing to the top of the screen.

RETURN VALUE

       0 for OK, otherwise an ggi-error(3) code.
