rpc_clear_server_binding(3ncs)											    rpc_clear_server_binding(3ncs)

Name
       rpc_clear_server_binding - unset the binding of an RPC handle to a server (client only)

Syntax
       #include <idl/c/rpc.h>

       void rpc_$clear_server_binding(handle, status)
       handle_t handle;
       status_$t *status;

Arguments
       handle		   The RPC handle whose binding is being cleared.

       status		   The completion status.  If the completion status returned in is equal to status_$ok , then the routine that supplied it
			   was successful.

Description
       The routine removes the association between an RPC handle and a particular server (that is, a particular port number), but does not  remove
       the associations with an object and with a host (that is, a network address).  This call replaces a fully bound handle with a bound-to-host
       handle.	A bound-to-host handle identifies an object located on a particular host but does not identify a server exporting an interface	to
       the object.

       If  a  client  uses  a bound-to-host handle to make a remote procedure call, the call is sent to the Local Location Broker (LLB) forwarding
       port at the host identified by the handle.  If the call's interface and the object identified by the handle are both  registered  with  the
       host's  LLB, the LLB forwards the request to the registering server.  When the client RPC runtime library receives a response, it binds the
       handle to the server.  Subsequent remote procedure calls that use this handle are then sent directly to the bound server's port.

       The routine is useful for client error recovery when a server dies.  The port that a server uses when it restarts is  not  necessarily  the
       same port that it used previously; therefore, the binding that the client was using may not be correct.	This routine enables the client to
       unbind from the dead server while retaining the binding to the host.  When the client sends a request, the binding is automatically set	to
       the server's new port.

Diagnostics
       This section lists status codes for errors returned by this routine in

       rpc_$not_in_call    An internal error.

       rpc_$proto_error    An internal protocol error.

Name
       rpc_register - register an interface (server only)

Syntax
       #include <idl/c/rpc.h>

       void rpc_$register(ifspec, epv, status)
       rpc_$if_spec_t *ifspec;
       rpc_$epv_t epv;
       status_$t *status;

Arguments
       ifspec		   The interface being registered.

       epv		   The entry point vector (EPV) for the operations in the interface.  The EPV is always defined in the server stub that is
			   generated by the NIDL compiler from an interface definition.

       status		   The completion status.  If the completion status returned in is equal to status_$ok , then the routine that supplied it
			   was successful.

Description
       The  routine  registers	an  interface  with  the RPC runtime library.  After an interface is registered, the RPC runtime library will pass
       requests for that interface to the server.

       You can call several times with the same interface (for example, from various subroutines of the same server), but each call  must  specify
       the  same  EPV.	Each registration increments a reference count for the registered interface; an equal number of routines are then required
       to unregister the interface.

Examples
       The following statement registers the bank interface with the bank server host's RPC runtime library:
       rpc_$register (&bank_$if_spec, bank_$server_epv, &status);

Diagnostics
       This section lists status codes for errors returned by this routine in

       rpc_$op_rng_error   The requested operation does not correspond to a valid operation in the requested interface.

       rpc_$too_many_ifs   The maximum number of interfaces is already registered with the RPC runtime library; the server  must  unregister  some
			   interface before it registers an additional interface.

       rpc_$not_in_call    An internal error.

       rpc_$you_crashed    This error can occur if a server has crashed and restarted.	A client RPC runtime library sends the error to the server
			   if the client makes a remote procedure call before the server crashes,  then  receives  a  response	after  the  server
			   restarts.

       rpc_$proto_error    An internal protocol error.

       rpc_$illegal_register
			   You are trying to register an interface that is already registered and you are using an EPV different from the one used
			   when the interface was first registered.  An interface can be multiply registered, but you must use	the  same  EPV	in
			   each routine.

       rpc_$bad_pkt	   The server or client has received an ill-formed packet.
