The client is a simple application that lets you send any kind of message to a particular destination. In this way, oyou can send a specific message to a specific destination in order to test its behaviour easily and quickly.
The destination could be either a MIHF or a MIH SAP (MIH-User/Link SAP).
The configuration of the client consists in defining the listening port of message's destination.
The listening port can be configured in two ways:
--port=<port number>
port = <port number>
It is possible to add new messages to the client with only 3 steps:
1st step: Define a new configuration option.
desc.add_options() // ... (kConf_MIH_NewMessage, "Send a New Message") ;
2nd step: Define the function responsible for creating and sending the message.
void send_newMessage(handler &sap, const char *dst)
{
mih::message p;
//...
// Define the message to send here
//...
sap.send(p);
}
3rd step: Add a condition in the main function to decide which message will be sent.
if (cfg.count(kConf_MIH_NewMessage)) {
std::cout << "sent a new message" << std::endl;
send_newMessage(sap, argv[1]);
}
Before running the client, the message option corresponding to the message that will be sent must be defined in the command line. In the next example, the client will send a MIH_Link_Up.indication message.
E.g.: ./client --indication.link_up
By default, message's destination is local-mihf. However, it is possible to send the message to another destination using the --dest option (in the command line).
After the client send the message the application will terminate.
