Tekkotsu: Wireless Class Reference

The networking interface needs more documentation. It also needs a cleanup. In the mean time, take a look at the TekkotsuMon objects in Tekkotsu/Behaviors/Mon. They all listen for new connections. Unfortunately, at the momement there are no examples of outgoing connections, but it should give you a pretty good idea how to start moving.

Constructor & Destructor Documentation

Wireless::Wireless ( )

constructor - only one wireless object is required per Aperios process.

MMCombo already creates one. The (global) instance is called wireless, and you can access it by including Wireless/Wireless.h (this file) in your code

void Wireless::BindCont ( void * msg )

callback function for communicating with Aperios Networking Toolkit. You should not call this.

Definition at line 255 of file Wireless.cc.

void Wireless::blockingSend ( int sock )

Bug:: This doesn't actually seem to block until the message is fully sent... a crash immediately after this will still cause a line or two to be dropped. This is still less dropped than regular send, but doesn't do much good for debugging until we fix this. (if we can...)

void Wireless::CloseCont ( void * msg )

int Wireless::connect	(	int	sock,
		const char *	ipaddr,

The socket tries to connect to a specific.

Tell the ipstack we want to recieve messages with this function.

bool Wireless::hasData ( int sock ) [inline]

utility function that you can use if you're curious about the state of the socket.

You shouldn't need to use it, since asking sockets for write and read buffers does the necessary sanity checks

int Wireless::listen	(	int	sock,
		int	port
	)

The socket waits for incoming connections.

That is, it acts like a server. If a connection is established and later broken, it resumes waiting for new connections if the socket's daemon flag is set.
