Detailed Description
A source of a type of observable event.
Signals are recognized points where significant events can be observed.
Compositors as well as the server can provide signals. Observers are
wl_listener's that are added through wl_signal_add. Signals are emitted
using wl_signal_emit, which will invoke all listeners until that
listener is removed by #wl_list_remove (or whenever the signal is
destroyed).

Parameters:
signal The signal that contains the specified listener
notify The listener that is the target of this search
Returns:
the list item that corresponds to the specified listener, or NULL
if none was found
