rpc_inq_object(3ncs)													      rpc_inq_object(3ncs)

Name
       rpc_inq_object - return the object UUID represented by an RPC handle (client or server)

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

       void rpc_$inq_object(handle, object, status)
       handle_t handle;
       uuid_$t *object;
       status_$t *status;

Arguments
       handle		   An RPC handle.

       object		   The UUID of the object identified by handle.

       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 enables a client or server to determine the particular object that a handle represents.

       If a server exports an interface through which clients can access several objects, it can use to determine the object requested in a  call.
       This routine requires an RPC handle as input, so the server can make the call only if the interface uses explicit handles (that is, if each
       operation in the interface has a handle parameter).  If the interface uses an implicit handle, the handle identifier is not passed  to  the
       server.

Examples
       A  database server that manages multiple databases must determine the particular database to be accessed whenever it receives a remote pro-
       cedure call.  Each manager routine makes the following call; the routine then uses the  returned  UUID  to  identify  the  database  to	be
       accessed:
       rpc_$inq_object (handle, &db_uuid, &status);

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

       rpc_$unk_if	   The	requested interface is not known.  It is not registered in the server, the version number of the registered inter-
			   face is different from the version number specified in the request, or the UUID in the request does not match the  UUID
			   of the registered interface.

       rpc_$not_in_call    An internal error.

       rpc_$proto_error    An internal protocol error.

rpc_alloc_handle(3ncs)													    rpc_alloc_handle(3ncs)

Name
       rpc_alloc_handle - create an RPC handle (client only)

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

       handle_t rpc_$alloc_handle(object, family, status)
       uuid_$t *object;
       unsigned long family;
       status_$t *status;

Arguments
       object		   The UUID of the object to be accessed.  If there is no specific object, specify uuid_$nil.

       family		   The address family to use in communications to access the object.  Currently, only socket_$ internet is supported.

       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 creates an unbound RPC handle that identifies a particular object but not a particular server or host.

       If a remote procedure call is made using the unbound handle, it will effect a broadcast to all Local Location Brokers (LLBs) on	the  local
       network.   If  the call's interface and the object identified by the handle are both registered with any LLB, that LLB forwards the request
       to the registering server.  The client RPC runtime library returns the first response that it receives and binds the handle  to	the  first
       responding server.

Examples
       The following statement allocates a handle that identifies the Acme company's payroll database object:
       h = rpc_$alloc_handle (&acme_pay_id, socket_$internet, &status);

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

       rpc_$comm_failure   The client was unable to get a response from the server.

       rpc_$unk_if	   The	requested interface is not known.  It is not registered in the server, the version number of the registered inter-
			   face is different from the version number specified in the request, or the UUID in the request does not match the  UUID
			   of the registered interface.

       rpc_$cant_create_sock
			   The RPC runtime library was unable to create a socket.

       rpc_$cant_bind_sock The RPC runtime library created a socket but was unable to bind it to a socket address.

       rpc_$wrong_boot_time
			   The	server	boot  time value maintained by the client does not correspond to the current server boot time.	The server
			   was probably rebooted while the client program was running.

       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.
