NAME

       XkbAllocGeomOverlayRows - Allocate rows in a overlay

SYNOPSIS

       Status XkbAllocGeomOverlayRows (XkbOverlayPtr overlay, int num_needed);

ARGUMENTS

       overlay
              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 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.

       XkbAllocGeomOverlayRows  allocates  num_needed  rows  and  adds  them  to the overlay.  No
       initialization of the rows is done.

       To free rows in an overlay, use XkbFreeGeomOverlayRows.

DIAGNOSTICS

       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
