Question 1

How do I build Async++ on Windows with Visual Studio?

Accepted Answer

Async++ supports Visual Studio 2013 and above. Detailed steps are in the Building and Installing wiki page, which covers compilation with MSVC and other Windows compilers.

Question 2

Can Async++ handle exceptions in asynchronous tasks?

Accepted Answer

Yes, exceptions can be propagated through tasks and caught using .get() or in continuation handlers, similar to std::future, but error handling might require careful design to avoid silent failures.

Question 3

Async++ vs std::async: which is better for my project?

Accepted Answer

Async++ offers more features like task composition and parallel algorithms, while std::async is simpler and standard. Choose Async++ for complex dependency chains or if you need parallel algorithms beyond basic async calls.

Question 4

How to implement a custom scheduler in Async++?

Accepted Answer

Use the low-level scheduler API described in the Schedulers wiki page to override task queuing and execution, allowing integration with existing thread management systems.

Question 5

Is Async++ suitable for real-time or embedded systems?

Accepted Answer

Probably not, as its task-based model may introduce non-deterministic overheads and relies on features like thread-local storage, which can be problematic on constrained platforms.

Question 6

What are the performance overheads compared to raw threads?

Accepted Answer

Async++ adds overhead for task management and scheduling, which is negligible for coarse-grained parallelism but might impact fine-grained tasks; profile to ensure it meets performance needs.
