XkbAllocGeomOverlayKeys(3)					   XKB FUNCTIONS					XkbAllocGeomOverlayKeys(3)

NAME
       XkbAllocGeomOverlayKeys - Allocate keys in an overlay row

SYNOPSIS
       Status XkbAllocGeomOverlayKeys (XkbOverlayRowPtr 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 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 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.

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
