Connects an I/O handler that watches a file descriptor.
bool io_handler(Glib::IOCondition io_condition) { ... } Glib::signal_io().connect(sigc::ptr_fun(&io_handler), fd, Glib::IO_IN | Glib::IO_HUP);
is equivalent to:
bool io_handler(Glib::IOCondition io_condition) { ... } 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());
| 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 handler 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. |
