XDrawPoint(3X11)                     SysV                     XDrawPoint(3X11)



NAME
     XDrawPoint, XDrawPoints - draw points

SYNTAX
     XDrawPoint(display, d, gc, x, y)
           Display *display;
           Drawable d;
           GC gc;
           int x, y;

     XDrawPoints(display, d, gc, points, npoints, mode)
           Display *display;
           Drawable d;
           GC gc;
           XPoint *points;
           int npoints;
           int mode;

ARGUMENTS
     d         Specifies the drawable.

     display   Specifies the connection to the X server.

     gc        Specifies the GC.

     mode      Specifies the coordinate mode. You can pass CoordModeOrigin or
               CoordModePrevious.

     npoints   Specifies the number of points in the array.

     points    Specifies a pointer to an array of points.

     x
     y         Specify the x and y coordinates where you want the point drawn.

DESCRIPTION
     The XDrawPoint function uses the foreground pixel and function components
     of the GC to draw a single point into the specified drawable; XDrawPoints
     draws multiple points this way.  CoordModeOrigin treats all coordinates
     as relative to the origin, and CoordModePrevious treats all coordinates
     after the first as relative to the previous point.  XDrawPoints draws the
     points in the order listed in the array.

     Both functions use these GC components: function, plane-mask, foreground,
     subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.

     XDrawPoint can generate BadDrawable, BadGC, and BadMatch errors.
     XDrawPoint can generate BadDrawable, BadGC, BadMatch, and BadValue
     errors.

DIAGNOSTICS
     BadDrawable
               A value for a Drawable argument does not name a defined Window
               or Pixmap.

     BadGC     A value for a GContext argument does not name a defined
               GContext.

     BadMatch  An InputOnly window is used as a Drawable.

     BadMatch  Some argument or pair of arguments has the correct type and

               range but fails to match in some other way required by the
               request.

     BadValue  Some numeric value falls outside the range of values accepted
               by the request.  Unless a specific range is specified for an
               argument, the full range defined by the argument's type is
               accepted.  Any argument defined as a set of alternatives can
               generate this error.
