XkbAddGeomOverlayRow(3)		 XKB FUNCTIONS	       XkbAddGeomOverlayRow(3)

NAME
       XkbAddGeomOverlayRow - Add a row	to an existing overlay

SYNOPSIS
       XkbOverlayRowPtr	XkbAddGeomOverlayRow (XkbOverlayPtr overlay, XkbRowPtr
	      row_under, int sz_keys);

ARGUMENTS
       - overlay
	      overlay to be updated

       - row_under
	      row to be	overlayed in the section overlay overlays

       - sz_keys
	      number of	keys to	reserve	in the row

DESCRIPTION
       Xkb provides functions to add a single new  element  to	the  top-level
       keyboard	 geometry. In each case	the num_ * fields of the corresponding
       structure is incremented	by 1. These functions do not change  sz_*  un-
       less  there  is no more room in the array. Some of these	functions fill
       in the values of	the element's structure	from the arguments. For	 other
       functions,  you must explicitly write code to fill the structure's ele-
       ments.

       The top-level geometry description includes a list of geometry  proper-
       ties.   A  geometry  property  associates  an  arbitrary	string with an
       equally arbitrary name. Programs	that display images of	keyboards  can
       use  geometry properties	as hints, but they are not interpreted by Xkb.
       No other	geometry structures refer to geometry properties.

       XkbAddGeomOverlayRow adds one row to the	overlay.  The new row contains
       space for sz_keys keys. If row_under specifies a	row that doesn't exist
       on  the	underlying  section,  XkbAddGeomOverlayRow  returns  NULL  and
       doesn't	change	the overlay.  XkbAddGeomOverlayRow returns NULL	if any
       of the parameters is empty or if	it was not able	to allocate space  for
       the overlay.

STRUCTURES
	   typedef struct _XkbOverlayRow {
	       unsigned	short	   row_under;	 /* index into the row under this overlay row */
	       unsigned	short	   num_keys;	 /* number of keys in the keys array */
	       unsigned	short	   sz_keys;	 /* size of the	keys array */
	       XkbOverlayKeyPtr	   keys;	 /* array of keys in the overlay row */
	   } XkbOverlayRowRec,*XkbOverlayRowPtr;
