NAME

       XkbAllocGeomOverlays - Allocate overlays in a section

SYNOPSIS

       Status XkbAllocGeomOverlays (XkbSectionPtr section, int num_needed);

ARGUMENTS

       - section
              section for which overlays should be allocated

       - num_needed
              number of new overlays required

DESCRIPTION

       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.

       XkbAllocGeomOverlays  allocates  num_needed  overlays  and  adds  them to the section.  No
       initialization of the overlays is done.

DIAGNOSTICS

       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
