Connects an I/O handler that watches a file descriptor.
is equivalent to:
This method is not thread-safe. You should call it, or manipulate the returned sigc::connection object, only from the thread where the SignalIO object's MainContext runs.
- 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()
returnsfalse
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.
- Returns
- A connection handle, which can be used to disconnect the handler.
