XkbAllocGeomOverlayKeys(3)       XKB FUNCTIONS      XkbAllocGeomOverlayKeys(3)

       XkbAllocGeomOverlayKeys - Allocate keys in an overlay row

       Status XkbAllocGeomOverlayKeys ( row, num_needed )
             XkbRowPtr 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  key-
       board  geometries.  Note that these functions merely allocate space for
       the new element(s), and it is up to you to fill in the  values  explic-
       itly  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  Bad-
       Value 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.

       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
