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 XWIN server.

gc Specifies the GC.

mode Specifies the coordinate mode. You can pass Coord-ModeOrigin 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 func-
     tion 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 gen-
          erate this error.
