 NAME

   dced_server_disable_if - Disables a service (rpc interface)
                            provided by a specific server on a
                            specific host

 SYNOPSIS

   #include <dce/dced.h>

   void dced_server_disable_if( dced_binding_handle_t  dced_bh,
                                uuid_t                 *exec_uuid,
                                rpc_if_id_t            *interface,
                                error_status_t         *status );

 PARAMETERS

   Input

   dced_bh
       Specifies the dced binding handle for the srvrexec service
       on a specific host.

   exec_uuid
       Specifies the UUID that dced uses to identify the running
       server.

   interface
       Specifies the RPC interface identifier that represents the
       service to be disabled.  The interface identifier is generated
       when idl compiles an interface definition file.  The interface
       identifier is an rpc_if_id_t structure that contains the
       interface UUID (uuid) of type uuid_t, and numbers of type
       unsigned16 representing the major (vers_major) and minor
       (vers_minor) version numbers for the interface.

   Output

   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
            db_s_bad_index_type
            db_s_iter_not_allowed
            db_s_readonly
            db_s_store_failed
            dced_s_bad_binding
            dced_s_not_found
            sec_acl_invalid_permission

 DESCRIPTION

   The dced_server_disable_if() routine disables a service provided
   by a server on a specific host.  A service is represented by an
   RPC interface identifier.  Management applications use this
   routine to remotely disable an interface so it is inaccessible by
   clients, without completely stopping the entire server.

   When a server starts and initializes itself, it must call the
   dce_server_register() routine to enable all of its services.
   The server can then disable its own individual services by using
   dce_server_disable_service().  This routine unregisters the
   service's interface from the RPC runtime and marks the interface
   as disabled in the endpoint map.  As an alternative, a management
   application can use dced_server_disable_if() to disable individual
   services.  However, this routine only affects the endpoint map in
   dced by marking the interface as disabled and does not affect the
   server's runtime.

   A management application can re-enable a service again by calling
   the dced_server_enable_if() routine.  (Servers re-enable their
   own services using the dce_server_enable_if() routine.)

   Prior to calling dced_server_disable_if(), the application must
   have established a valid dced binding handle to the srvrexec
   service by calling either dced_binding_create() or
   dced_binding_from_rpc_binding().
