The following example illustrates creating a service which other applications can connect to.

void

server_example()

{ int ipc_id;

if ((ipc_id = ipc_create(IPC_TCP, "1234")) < 0) {

message("Failed to create server port");

return;

}

/* Register macro to handle new incoming connections. */

/* Note: we pass in the ipc_id as an argument so the */

/* callback knows which connection to use. */

ipc_register(ipc_id, IPC_TRIGGER_READ,

"new_connection " + ipc_id);

}

void

new_connection(int ipc_id)

{ int ipc_id2;

stringstr;

if ((ipc_id2 = ipc_accept(ipc_id)) < 0) {

message("Failed to handle new connection request.");

return;

}

/* Read message request from the remote client */

str = ipc_read(ipc_id2);

message("Received '%s'", str);

/* Close down the connection */

ipc_close(ipc_id2);

}
