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 or

       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 function uses the foreground pixel and function components of the GC to draw a single point into the specified drawable; draws multiple
       points this way.  treats all coordinates as relative to the origin, and treats all coordinates after the first as relative to the previous
       point.  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.

       can generate and errors.  can generate and errors.

Structures
       The 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
       A value for a Drawable argument does not name a defined Window or Pixmap.

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

       An	 window is used as a Drawable.

       Some argument or pair of arguments has the correct type and range but fails
		 to match in some other way required by the request.

       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.

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 argu-
		 ment, the full range defined by the argument's type is accepted.  Any argument defined as a set of alternatives can generate this
		 error.
