NAME
       XParseGeometry, XWMGeometry - parse window geometry

SYNTAX
       int XParseGeometry(parsestring, x_return, y_return,
       width_return, height_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;

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

       user_geom Specifies the user-specified geometry or NULL.

DESCRIPTION
       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:

       [=][<width>{xX}<height>][{+-}<xoffset>{+-}<yoffset>]

       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-
       dent.

       The XParseGeometry function returns a bitmask that indi-
       cates 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 represented by XValue,
       YValue, WidthValue, HeightValue, XNegative, or YNegative
       and are defined in <X11/Xutil.h>.  They will be set when-
       ever 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 (usu-
       ally the ones to be stored in WM_NORMAL_HINTS) and returns
       the position, size, and gravity (NorthWestGravity,
       NorthEastGravity, SouthEastGravity, or SouthWestGravity)
       that describe the window.  If the base size is not set in
       the XSizeHints 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 structure, the base size is used.
       A mask (in the form returned by XParseGeometry) 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 grav-
       ity_return to update the hints directly.
