rpc_inq_binding(3ncs)
Name
rpc_inq_binding − return the socket address represented by an RPC handle (client or server)
Syntax
#include <idl/c/rpc.h>
void rpc_$inq_binding(handle, sockaddr, slength, status)
handle_t handle;
socket_$addr_t *sockaddr;
unsigned long *slength;
status_$t *status;
Arguments
handle An RPC handle.
sockaddr The socket address represented by handle.
slength The length, in bytes, of sockaddr.
status The completion status. If the completion status returned in status.all is equal to status_$ok , then the routine that supplied it was successful.
Description
The rpc_$inq_binding routine enables a client to determine the socket address, and therefore the server, identified by an RPC handle. It is useful when a client uses an unbound handle in a remote procedure call and wishes to determine the particular server that responded to the call.
Examples
The Location Broker administrative tool, lb_admin, uses the following statement to determine the GLB that last responded to a lookup request:
rpc_$inq_binding(lb_$handle, &global_broker_addr,
&global_broker_addr_len, &status);
Diagnostics
This section lists status codes for errors returned by this rpc_$ routine in status.all.
rpc_$not_in_call An internal error.
rpc_$proto_error An internal protocol error.
rpc_$unbound_handle
The handle is not bound and does not represent a particular host address. Returned by rpc_$inq_binding.
