XDrawPoint(3)			XLIB FUNCTIONS			 XDrawPoint(3)

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

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

       int  XDrawPoints(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	compo-
       nents  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.	XDraw-
       Points draws the	points in the order listed in the array.

       Both  functions	use  these  GC components: function, plane-mask, fore-
       ground, 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 er-
       rors.

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 Win-
		 dow or	Pixmap.

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

       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.
