Connects an I/O handler.
Glib::signal_io().connect(sigc::ptr_fun(&io_handler), fd, Glib::IO_IN | Glib::IO_HUP);
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 falsethe signal is disconnected.fd The file descriptor (or a HANDLEon 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.

Connects an I/O channel.
Glib::signal_io().connect(sigc::ptr_fun(&io_handler), channel, Glib::IO_IN | Glib::IO_HUP);
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 falsethe 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.
