XDrawPoint(3X11)            X Version 11(Release 5)            XDrawPoint(3X11)


NAME
      XDrawPoint, XDrawPoints, XPoint - draw points and points structure

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

STRUCTURES
      The XPoint structure contains:

      typedef struct {
           short x, y;
      } XPoint;

      All x and y members are signed integers.  The width and height members
      are 16-bit unsigned integers.  You should be careful not to generate
      coordinates and sizes out of the 16-bit ranges, because the protocol only
      has 16-bit fields for these values.

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.
