// @interface
|
||
|
|
// Create new zproxy actor instance. The proxy switches messages between
|
||
|
|
// a frontend socket and a backend socket; use the FRONTEND and BACKEND
|
||
|
|
// commands to configure these:
|
||
|
|
//
|
||
|
|
// zactor_t *proxy = zactor_new (zproxy, NULL);
|
||
|
|
//
|
||
|
|
// Destroy zproxy instance. This destroys the two sockets and stops any
|
||
|
|
// message flow between them:
|
||
|
|
//
|
||
|
|
// zactor_destroy (&proxy);
|
||
|
|
//
|
||
|
|
// Note that all zproxy commands are synchronous, so your application always
|
||
|
|
// waits for a signal from the actor after each command.
|
||
|
|
//
|
||
|
|
// Enable verbose logging of commands and activity:
|
||
|
|
//
|
||
|
|
// zstr_send (proxy, "VERBOSE");
|
||
|
|
// zsock_wait (proxy);
|
||
|
|
//
|
||
|
|
// Specify frontend socket type -- see zsock_type_str () -- and attach to
|
||
|
|
// endpoints, see zsock_attach (). Note that a proxy socket is always
|
||
|
|
// serverish:
|
||
|
|
//
|
||
|
|
// zstr_sendx (proxy, "FRONTEND", "XSUB", endpoints, NULL);
|
||
|
|
// zsock_wait (proxy);
|
||
|
|
//
|
||
|
|
// Specify backend socket type -- see zsock_type_str () -- and attach to
|
||
|
|
// endpoints, see zsock_attach (). Note that a proxy socket is always
|
||
|
|
// serverish:
|
||
|
|
//
|
||
|
|
// zstr_sendx (proxy, "BACKEND", "XPUB", endpoints, NULL);
|
||
|
|
// zsock_wait (proxy);
|
||
|
|
//
|
||
|
|
// Capture all proxied messages; these are delivered to the application
|
||
|
|
// via an inproc PULL socket that you have already bound to the specified
|
||
|
|
// endpoint:
|
||
|
|
//
|
||
|
|
// zstr_sendx (proxy, "CAPTURE", endpoint, NULL);
|
||
|
|
// zsock_wait (proxy);
|
||
|
|
//
|
||
|
|
// Pause the proxy. A paused proxy will cease processing messages, causing
|
||
|
|
// them to be queued up and potentially hit the high-water mark on the
|
||
|
|
// frontend or backend socket, causing messages to be dropped, or writing
|
||
|
|
// applications to block:
|
||
|
|
//
|
||
|
|
// zstr_sendx (proxy, "PAUSE", NULL);
|
||
|
|
// zsock_wait (proxy);
|
||
|
|
//
|
||
|
|
// Resume the proxy. Note that the proxy starts automatically as soon as it
|
||
|
|
// has a properly attached frontend and backend socket:
|
||
|
|
//
|
||
|
|
// zstr_sendx (proxy, "RESUME", NULL);
|
||
