Public Member Functions
	vrpn_Button_Server (const char name, vrpn_Connection c, int numbuttons=1)

int	number_of_buttons (void)
	Tells how many buttons there are (may be clipped to MAX_BUTTONS)

virtual void	mainloop ()
	Called once each time through the server program's mainloop to handle various functions (like setting toggles, reporting changes, etc).

int	set_button (int button, int new_value)
	Allows the server program to set current button states (to 0 or 1)

void	print (void)

Public Member Functions inherited from vrpn_BaseClass
	vrpn_BaseClass (const char name, vrpn_Connection c=NULL)
	Names the device and assigns or opens connection, calls registration methods.

virtual	~vrpn_BaseClass ()

Public Member Functions inherited from vrpn_BaseClassUnique
	vrpn_BaseClassUnique ()

virtual	~vrpn_BaseClassUnique ()
	Unregister all of the message handlers that were to be autodeleted.

vrpn_Connection *	connectionPtr ()
	Returns a pointer to the connection this object is using.

Protected Member Functions inherited from vrpn_Button_Filter
	vrpn_Button_Filter (const char , vrpn_Connection c=NULL)

virtual vrpn_int32	encode_states_to (char *buf)
	Encode a message describing the state of all buttons.

virtual void	report_changes (void)

Protected Member Functions inherited from vrpn_Button
virtual int	register_types (void)
	Register the types of messages this device sends/receives. Return 0 on success, -1 on fail.

virtual void	report_states (void)

virtual vrpn_int32	encode_to (char *buf, vrpn_int32 button, vrpn_int32 state)
	Encode a message describing the new state of a button.

Protected Member Functions inherited from vrpn_BaseClass
virtual int	init (void)
	Initialize things that the constructor can't. Returns 0 on success, -1 on failure.

virtual int	register_senders (void)
	Register the sender for this device (by default, the name of the device). Return 0 on success, -1 on fail.

Protected Member Functions inherited from vrpn_BaseClassUnique
int	register_autodeleted_handler (vrpn_int32 type, vrpn_MESSAGEHANDLER handler, void *userdata, vrpn_int32 sender=vrpn_ANY_SENDER)
	Registers a handler with the connection, and remembers to delete at destruction.

int	send_text_message (const char *msg, struct timeval timestamp, vrpn_TEXT_SEVERITY type=vrpn_TEXT_NORMAL, vrpn_uint32 level=0)
	Sends a NULL-terminated text message from the device d_sender_id.

SendTextMessageBoundCall	send_text_message (vrpn_TEXT_SEVERITY type=vrpn_TEXT_NORMAL)
	Returns an object you can stream into to send a text message from the device like send_text_message(vrpn_TEXT_WARNING) << "Value of i is: " << i; This use requires including vrpn_SendTextMessageStreamProxy.h.

void	server_mainloop (void)
	Handles functions that all servers should provide in their mainloop() (ping/pong, for example) Should be called by all servers in their mainloop()

void	client_mainloop (void)
	Handles functions that all clients should provide in their mainloop() (warning of no server, for example) Should be called by all clients in their mainloop()
