ggiWaitRayPos(3) GGI ggiWaitRayPos(3)NAMEggiWaitRayPos : Wait for the raster to reach a point
SYNOPSIS
#include <ggi/misc.h>
int ggiWaitRayPos(ggi_visual_t src, int32_t* x, int32_t* y);
DESCRIPTIONggiWaitRayPos will wait, as best supported by the target, until the
raster reaches a certain point on the screen. Actual integer coordi‐
nates don't mean anything under current implementations, and the units
the coordinates are provided in haven't been firmly decided. Instead,
use one of the following macros: 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; GGI_RP_DONTCARE means you don't care where the
raster is in this direction.
RETURN VALUE
0 for OK, otherwise an ggi-error(3) code. In the event that there is
an error, it is most likely that the implementation on the given target
is limited. In this case, the parameters x, y will be assigned values
equal to one of the above macros, which should work on the target, sup‐
posing using those values actually accomplishes what you want to do.
