NAME

       XkbAllocGeomKeys - Allocate space for an arbitrary number of keys to a row

SYNOPSIS

       Status XkbAllocGeomKeys (XkbRowPtr row, int num_needed);

ARGUMENTS

       - row  row to which keys should be allocated

       - num_needed
              number of new keys 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.

       XkbAllocGeomKeys 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
