Threadsafe C++ signals done right : cpp - reddit.com Indeed. Qt signal/slot are specifically designed to make threads easy. You just write the code with signals and then, depending on the thread where the objects are created at the beginning (or to which thread they are moved), same signals act as direct calls or as message queues. Boost: what exactly is not threadsafe in Boost.Signals? It doesn't seem to be like Qt, in which the thread a certain slot's code gets run on is based on the target slot's "thread affinity" (which means emitting a signal can trigger slots on many different threads to run in parallel.) But I guess not supporting that is why the boost::signal "combiners" can do things like this. c++ - Is it safe to emit signal from another thread ... Is it safe to emit a signal on an object from another thread (if the slot is connected as QueuedConnection)?I couldn't find a specific piece of documentation that would mention this, the most relevant quote I found is this:. QObject is reentrant.
Then create a private slot in your main class that takes no args and connect it to your worker thread's start() signal. Inside your private slot calli want to avoid keeping member in the Worker object for the pFoo ref to pointer. im confused here what do you mean ? .. ok gotyou .. is it thread safe ?

Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots.
Thread-Safety - 1.43.0 - boost.org It is expected that slot objects will be created then connected to a signal in a single thread. Once they have been copied into a signal's slot list, they are protected by the mutex associated with each signal-slot connection. The signals2::trackable class does NOT provide thread-safe automatic connection management. In particular, it leaves ... std::signal - cppreference.com POSIX requires that signal is thread-safe, and specifies a list of async-signal-safe library functions that may be called from any signal handler. Signal handlers are expected to have C linkage and, in general, only use the features from the common subset of C and C++. It is implementation-defined if a function with C++ linkage can be used as a ... C Thread Safe and Reentrant Function Examples Re-entrance and thread-safety are two different concepts that can be associated with good programming practices. In this article we will try and understand both the concepts and their differences with the help of some code snippets. As the name suggests, a piece of code is thread safe when more than ...

vdk-signals C++ signals and slots. vdk-signals is a type-safe and thread-safe signals-slots system for standard C++ designed with performance and simplicity in mind. It follows the main philosophy of the C++ language avoiding unnecessary overheads and superfluous functionality that can slow down your program.
If you've ever used Qt to build a GUI, you're probably familiar with their signal/slots implementation. For me, it was my first encounter with the idiom and I really liked it. The design made me feel like I could have different elements interact with eachother without them even being aware of ...
signals-cpp . Provide a very simple header-only C++ interface for creating and managing signal-slot-connections in an easy and thread-safe manner. misc. This library is header-only and uses some new C++11 features (such as std::mutex, std::atomic, lambda-expressions, and ...) to provide an easy-to-use interface and being thread-safe at the same ...
