 NAME

   dced_binding_from_rpc_binding - Establishes a dced binding to one
                                   of the host services on the host
                                   specified in an existing RPC binding
                                   handle.

 SYNOPSIS

   #include <dce/dced.h>

   void dced_binding_from_rpc_binding( dced_service_type_t   service,
                                       handle_t              rpc_bh,
                                       dced_binding_handle_t *dced_bh,
                                       error_status_t        *status );

 PARAMETERS

   Input

   service
       A variable that specifies one of the host services.  A valid
       variable name includes one of the following:

            dced_e_service_type_hostdata
            dced_e_service_type_srvrconf
            dced_e_service_type_srvrexec
            dced_e_service_type_secval
            dced_e_service_type_keytab

    rpc_bh
       An RPC binding handle to some server.

   Output

   dced_bh
       Returns a dced binding handle which is a pointer to an opaque
       data structure containing information about an RPC binding, the
       host, the host service, and a local cache.

   status
       Returns the status code from this routine.  This status code
       indicates whether the routine completed successfully or, if not,
       why not.  The possible status codes are:

            error_status_ok
            dced_s_no_memory
            dced_s_unknown_service
            ept_s_cant_perform_op
            ept_s_database_invalid
            ept_s_invalid_context
            ept_s_invalid_entry
            rpc_s_comm_failure
            rpc_s_fault_context_mismatch
            rpc_s_invalid_arg
            rpc_s_invalid_binding
            rpc_s_no_more_elements
            rpc_s_wrong_kind_of_binding

 DESCRIPTION

   The dced on each DCE host maintains the host services and provides
   a remote interface to the services.  The
   dced_binding_from_rpc_binding() routine establishes a dced binding
   to a dced service, and it (or dced_binding_create()) must be the
   first dced API routine called before an application can access one
   of the host services with other dced routines.  When an application
   is finished with the service, it should call the dced_binding_free()
   routine to free resources.

   Prior to using the RPC binding in this routine, make a copy of the
   binding by using the rpc_binding_copy() routine.  This is necessary
   if the application needs to continue using the RPC binding because
   otherwise the dced binding takes over the RPC binding.

   The RPC binding may be obtained from a call to specific RPC
   runtime routines such as rpc_binding_from_string_binding,
   rpc_ns_binding_import_next, or rpc_ns_binding_lookup_next.

 EXAMPLES

   This example obtains an RPC binding from a string binding,
   and it later makes a copy of the RPC binding for use in the
   dced_binding_from_rpc_binding() call.

        dced_binding_handle_t   dced_bh;
        dced_service_type_t     service_type;
        error_status_t          status;
        unsigned_char_t         string_binding[STRINGLEN];
         .
         .
         .
        rpc_binding_from_string_binding( string_binding,
                                         &binding_handle,
                                         &status );
         .
         .
         .
        rpc_binding_copy( binding_handle, &rpc_bh, &status );
        dced_binding_from_rpc_binding( service_type,
                                       rpc_bh,
                                       &dced_bh,
                                       &status );
         .
         . /* Other routines including dced API routines. */
         .
        dced_binding_free(dced_bh, &status);
