RpcService(3)
support RPC between a service and its clients
SYNOPSIS
#include <Dispatch/rpcservice.h>
DESCRIPTION
An RpcService (actually, an instance of a derived class) creates a port
and listens to it for connections from clients. When a client opens a
connection, the RpcService will create a reader to handle RPC requests
from the connection.
CONSTRUCTORS
- RpcService(int port)
-
- RpcService(const char* path, int port = 0)
-
Start up an RPC service. If a filename is given, record the RPC
service's hostname and port number in it so clients can contact the
service. If ``port'' is zero, the next free port number will be used.
PUBLIC OPERATIONS
- void run()
-
- void quitRunning()
-
Read RPC requests continuously until ``quitRunning()'' terminates the
loop. If you're using InterViews, you don't have to call ``run()''
since the InterViews event-reading code will also read RPC requests.
PROTECTED OPERATIONS
- virtual void createReader(int fd) = 0
-
You must define this function in a derived class in order to start
servicing RPC requests from a new client. Typically all you have to
do is to construct a reader using the passed file descriptor and make
the reader responsible for deleting itself when it notices that the
connection has been closed by the client.
