◆ CallFunctionInValidationInterfaceQueue()

void CallFunctionInValidationInterfaceQueue ( std::function< void()>  func)

Pushes a function to callback onto the notification queue, guaranteeing any callbacks generated prior to now are finished when the function is called.

Be very careful blocking on func to be called if any locks are held - validation interface clients may not be able to make progress as they often wait for things like cs_main, so blocking until func is called with cs_main will result in a deadlock (that DEBUG_LOCKORDER will miss).
