       XkbAllocGeomOverlayKeys - Allocate keys in an overlay row


       Status XkbAllocGeomOverlayKeys (XkbOverlayRowPtr row, int num_needed);


       - row  section for which rows should be allocated

       - num_needed
              number of new rows required


       Xkb  provides  a  number  of  functions  to  allocate and free subcomponents of a keyboard
       geometry. Use these functions to create or modify keyboard  geometries.  Note  that  these
       functions 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
       initialization of the keys is done.
