Boost signal disconnect all slots

The Boost.Signals library is an implementation of a managed signals and slots system.Signals and slots are managed, in that signals and slots (or, more properly, objects that occur as part of the slots) track all connections and are capable of automatically disconnecting signal/slot connections... Signal and Slots - kjellkod | Boost.Signals Signal and slots is a concept developed from Qt. It is basically a generalized implementation of the Observer pattern (see also publisher/subscriber) The purpose of the KjellKod signal-n-slot is to have the power of Observer pattern - but made with generic function callback.

Furthermore, FD.Delegate is a Boost.Function 'drop-in' replacement. So instead, we use the equal_to() member function for an equality comparison between two delegates.

Example 67.12 accesses s twice, but the lambda function is only called the second time. The program writes Hello, world! to the standard output stream only once.. Because false is passed to the constructor as the second parameter, the first object of type boost::signals2::shared_connection_block does not block the connection to the signal s.Hence, calling blocking() on the object b1 returns false.

boost signals allows temporarily blocking a connection via a connection member function. However, I have a single signal with many connections.I don't know of any way to do that directly. If you are willing to permanently disconnect all slots, you can use the disconnect_all_slots() method.
