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
