DDXPointRec(D4nfb)
DDXPointRec --
DDX point record structure
Synopsis
#include "miscstruct.h"
Description
Structure definition
typedef struct _DDXPoint {
short x, y;
} DDXPointRec;
Structure members
The members are
x,y-
The DDXPointRec structure
records a specific location in the frame buffer.
The structure has two members:
x
and y
.
Usage
The DDXPointRec structure
defines the starting coordinates for polygons,
solid spans, and rectangles.
It ensures that, when multiple rectangles are filled
in different parts of a window and overlap,
the patterns will match up appropriately.
A simple analogy of this would be
when you are putting wallpaper up and need to make sure that
the wallpaper pattern matches as you paper each strip to the wall.
Version applicability
This structure is supported for NFB drivers
on all releases of SCO OpenServer 5, SVR5, and AIX 5L.
Examples
