       XParseGeometry, XWMGeometry - parse window geometry

       int XParseGeometry(parsestring, x_return, y_return, width_return,
	     char *parsestring;
	     int *x_return, *y_return;
	     unsigned int *width_return, *height_return;

       int XWMGeometry(display,	screen,	user_geom, def_geom, bwidth, hints,
       x_return, y_return,
		       width_return, height_return, gravity_return)
	     Display *display;
	     int screen;
	     char *user_geom;
	     char *def_geom;
	     unsigned int bwidth;
	     XSizeHints	*hints;
	     int *x_return, *y_return;
	     int *width_return;
	     int *height_return;
	     int *gravity_return;

		 Specify the geometry specifications.

       display	 Specifies the connection to the X server.

       fwidth	 Specify the font height and width in pixels (increment	size).

		 Specifies the string you want to parse.

       screen	 Specifies the screen.

		 Return	the width and height determined.

       yadder	 Specify additional interior padding needed in the window.

       y_return	 Return	the x and y offsets.

       bwidth	 Specifies the border width.

       hints	 Specifies the size hints for the window in its	normal state.

       def_geom	 Specifies the application's default geometry or NULL.

		 Returns the window gravity.

       user_geom Specifies the user-specified geometry or NULL.

       By convention, X	applications use a standard string to indicate window
       size and	placement.  XParseGeometry makes it easier to conform to this
       standard	because	it allows you to parse the standard window geometry.
       Specifically, this function lets	you parse strings of the form:


       The fields map into the arguments associated with this function.
       (Items enclosed in <> are integers, items in [] are optional, and items
       enclosed	in {} indicate ``choose	one of.''  Note	that the brackets
       should not appear in the	actual string.)	 If the	string is not in the
       Host Portable Character Encoding, the result is implementation-depen-

       The XParseGeometry function returns a bitmask that indicates which of
       the four	values (width, height, xoffset,	and yoffset) were actually
       found in	the string and whether the x and y values are negative.	 By
       convention, -0 is not equal to +0, because the user needs to be able to
       say ``position the window relative to the right or bottom edge.''  For
       each value found, the corresponding argument is updated.	 For each
       value not found,	the argument is	left unchanged.	 The bits are repre-
       sented by XValue, YValue, WidthValue, HeightValue, XNegative, or	YNega-
       tive and	are defined in <X11/Xutil.h>.  They will be set	whenever one
       of the values is	defined	or one of the signs is set.

       If the function returns either the XValue or YValue flag, you should
       place the window	at the requested position.

       The XWMGeometry function	combines any geometry information (given in
       the format used by XParseGeometry) specified by the user	and by the
       calling program with size hints (usually	the ones to be stored in
       WM_NORMAL_HINTS)	and returns the	position, size,	and gravity (North-
       WestGravity, NorthEastGravity, SouthEastGravity,	or SouthWestGravity)
       that describe the window.  If the base size is not set in the XSize-
       Hints structure,	the minimum size is used if set.  Otherwise, a base
       size of zero is assumed.	 If no minimum size is set in the hints	struc-
       ture, the base size is used.  A mask (in	the form returned by XParseGe-
       ometry) that describes which values came	from the user specification
       and whether or not the position coordinates are relative	to the right
       and bottom edges	is returned.  Note that	these coordinates will have
       already been accounted for in the x_return and y_return values.

       Note that invalid geometry specifications can cause a width or height
       of zero to be returned.	The caller may pass the	address	of the hints
       win_gravity field as gravity_return to update the hints directly.
