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
