rrpc_are_you_there() rrpc_are_you_there()
Name
rrpc_are_you_there - check whether a server is answering requests
Format
#include <rrpc.h>
void rrpc_$are_you_there( handle, *status)
handle_t handle;
status_$t *status;
Arguments
handle A remote procedure call (RPC) handle.
status The completion status.
Description
The call checks whether a server is answering requests.
Restrictions
On the client side, because of the way the calls are defined and implemented in the run-time library you must explicitly call into the
entry point vector table for the interface to send an request across the network. The following is an example of a call that works as
desired.
(*rrpc_$client_epv.rrpc_$are_you_there)(handle, &status);
The server side stub routine calls the entry point on behalf of the client. The results of the call are then passed back to the client.

rpc_clear_binding(3ncs)rpc_clear_binding(3ncs)Name
rpc_clear_binding - unset the binding of an RPC handle to a host and server (client only)
Syntax
#include <idl/c/rpc.h>
void rpc_$clear_binding(handle, status)
handle_t handle;
status_$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_$ok , then the routine that supplied it was success-
ful.
Description
The routine removes any association between an RPC handle and a particular server and host, but it does not remove the association between
the handle and an object. This routine saves the RPC handle so that it can be reused to access the same object, either by broadcasting or
after resetting the binding to another server.
A remote procedure call made using an unbound handle is broadcast to all Local Location Brokers (LLBs) on the local network. If the call's
interface and the object identified by the handle are both registered with any LLB, that LLB forwards the request to the registering
server. The client RPC runtime library returns the first response that it receives and binds the handle to the first server that
responded.
The routine is the inverse of the routine.
Examples
Clear the binding represented in handle:
rpc_$clear_binding (handle, &status);
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.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)

In other words is there kind of an equal Linux with Unix?

I noticed my hostname is <my-full-name>s-macbook.local. I'm not sure exactly what information leaves the local network, and whether the hostname is included, but if it is, this would mean people on the Internet can look at my hostname and see who I am.
