sigc::connection Glib::SignalIO::connect	(	const sigc::slot<bool, IOCondition>&	slot,
		int	fd,
		IOCondition	condition,
		int	priority = PRIORITY_DEFAULT
	)

Connects an I/O handler.

 Glib::signal_io().connect(sigc::ptr_fun(&io_handler), fd, Glib::IO_IN | Glib::IO_HUP);

is equivalent to:

 const Glib::RefPtr<Glib::IOSource> io_source = Glib::IOSource::create(fd, Glib::IO_IN | Glib::IO_HUP);
 io_source->connect(sigc::ptr_fun(&io_handler));
 io_source->attach(Glib::MainContext::get_default());

Parameters:

	slot	A slot to call when polling fd results in an event that matches condition. The event will be passed as a parameter to slot. If io_handler returns false the signal is disconnected.
	fd	The file descriptor (or a HANDLE on Win32 systems) to watch.
	condition	The conditions to watch for.
	priority	The priority of the new event source.

Returns:

A connection handle, which can be used to disconnect the handler.

sigc::connection Glib::SignalIO::connect	(	const sigc::slot<bool, IOCondition>&	slot,
		const Glib::RefPtr<IOChannel>&	channel,
		IOCondition	condition,
		int	priority = PRIORITY_DEFAULT
	)

Connects an I/O channel.

 Glib::signal_io().connect(sigc::ptr_fun(&io_handler), channel, Glib::IO_IN | Glib::IO_HUP);

is equivalent to:

 const Glib::RefPtr<Glib::IOSource> io_source = Glib::IOSource::create(channel, Glib::IO_IN | Glib::IO_HUP);
 io_source->connect(sigc::ptr_fun(&io_handler));
 io_source->attach(Glib::MainContext::get_default());

Parameters:

	slot	A slot to call when polling channel results in an event that matches condition. The event will be passed as a parameter to slot. If io_handler returns false the signal is disconnected.
	channel	The IOChannel object to watch.
	condition	The conditions to watch for.
	priority	The priority of the new event source.

Returns:

A connection handle, which can be used to disconnect the handler.
