/sys$common/syshlp/helplib.hlb RPC, rpccp, remove_mapping, DESCRIPTION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

         The remove mapping command removes one or more elements from
         an endpoint map.  The target endpoint map can be either the
         local endpoint map or the endpoint map of a specified remote
         host.  Each map element corresponds to an object UUID,
         interface identifier, annotation (optional), and binding
         information. The binding information contains an RPC
         protocol sequence, a network address, and an endpoint within
         brackets (rpc-prot-seq:network-addr[endpoint]).

         If entered without a remote host address as an argument, the
         command operates on the local endpoint map.  This command
         requires one interface identifier (the -i option); at least
         one string binding (the -b option); and, optionally, one or
         more object UUIDs (the -o option). Each instance of the
         command accepts from 1 to 32 -b options and from 0 to 32 -o
         options. The options work together to delimit the elements
         to be removed from the target endpoint map. The command
         removes any map element that contains the specified
         interface identifier, a specified string binding, and a
         specified object UUID (if any).
