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 rela-
       tive to the origin, and CoordModePrevious treats all coor-
       dinates 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,


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 cor-
                 rect 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 spe-
                 cific 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.
