XkbAllocGeomOverlayKeys(3)		  XKB FUNCTIONS 	       XkbAllocGeomOverlayKeys(3)

NAME
       XkbAllocGeomOverlayKeys - Allocate keys in an overlay row

SYNOPSIS
       Status XkbAllocGeomOverlayKeys ( row, num_needed )
	     XkbRowPtr row;
	     int num_needed;

ARGUMENTS
       - row  section for which rows should be allocated

       - num_needed
	      number of new rows required

DESCRIPTION
       Xkb provides a number of functions to allocate and free subcomponents of a keyboard geome-
       try. Use these functions to create or modify keyboard geometries. Note  that  these  func-
       tions  merely  allocate	space  for the new element(s), and it is up to you to fill in the
       values explicitly in your code. These allocation functions increase sz_* but  never  touch
       num_* (unless there is an allocation failure, in which case they reset both sz_* and num_*
       to zero). These functions return Success if they succeed, BadAlloc if they are not able to
       allocate space, or BadValue if a parameter is not as expected.

       XkbAllocGeomOverlayKeys	allocates  num_needed keys and adds them to the row.  No initial-
       ization of the keys is done.

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
