 *  _Objects_Name_to_id

 *

 *  These kernel routines search the object table(s) for the given

 *  object name and returns the associated object id.

 *

 *  Input parameters:

 *    information - object information

 *    name        - user defined object name

 *    node        - node indentifier (0 indicates any node)

 *    id          - address of return ID

 *

 *  Output parameters:

 *    id                 - object id

 *    OBJECTS_SUCCESSFUL - if successful

 *    error code         - if unsuccessful
