C++ signal slot thread safe

By Mark Zuckerberg

A thread-safe method may be called from different threads simultaneously. In cases where there is usually no concurrent access to methods, calling non-thread-safe methods of objects in other threads may work thousands of times before a concurrent access occurs, causing unexpected behavior.

I'm implementing a Signal/Slot framework, and got to the point that I want it to be thread-safe.When is a signal/slot implementation (or any framework that calls functions outside itself, specified in some way by the user) considered... vdksoft/signals - Libraries.io | C++ Signals & Slots… The signals and slots mechanism is type safe. The signal type must match the signature of the receiving slot and the compiler helps to detect typeHigh speed is achieved through the use of modern C++ features and atomic variables to ensure thread-safety and fastest possible execution. How Qt Signals and Slots Work The Qt signals/slots and property system are based on the ability to introspect the objects at runtime.Can you spot the keywords that are not pure C++ keywords? signals, slots, Q_OBJECT, emit, SIGNAL, SLOT.

SignalsandSlots in C++ SarahThompson∗ March2002 1 Introduction This paper introduces the sigslot library, which implements a type-safe, thread-safe signal/slot mech-anism in C++. The library is implemented entirely in C++, and does not require source code to be pre-processed1 in order for itto be used.
