XParseGeometry(3)		XLIB FUNCTIONS		     XParseGeometry(3)

NAME
       XParseGeometry, XWMGeometry - parse window geometry

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

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

ARGUMENTS
       position
       default_position
		 Specify the geometry specifications.

       display	 Specifies the connection to the X server.

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

       parsestring
		 Specifies the string you want to parse.

       screen	 Specifies the screen.

       width_return
       height_return
		 Return the width and height determined.

       xadder
       yadder	 Specify additional interior padding needed in the window.

       x_return
       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.

       gravity_return
		 Returns the window gravity.

       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 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.
