7 Programming with RPC 1.2.1 on

MPE/iX

This chapter explains the RPC application programming with a small

example. The example consists of server and client components. The

client makes a RPC request to the server and asks the server to sleep

for a speciﬁed amount of time. The server serves this request from the

client by going to sleep for the time given by the client.

/* client.c

************************************************************************************

* This is the sleeper client program.It takes two arguments, a hostname to contact

* for the server and a number of seconds to sleep. The client locates the server

* using the hostname provided and the endpoint mapper on the server's host -- the

* client does not contact the name service for server location information. The

* client uses the explicit binding method, so it uses th hostname argument to

* construct a binding handle (rpc_binding_handle_t).The client passes this binding

* handle to the invocation of the remote procedure.
