Threading

Simulant ships its own set of threading primitives for portability. All of these primitives exist in the smlt::thread namespace.

Thread

smlt::thread::Thread exists in the threads/thread.h header file and let's you spawn a thread.

Atomic<T>

smlt::thread::Atomic<T> exists in the threads/atomic.h header file and lets you perform mutex protected operations on a wrapped type.

async and Future<T>

smlt::thread::async allows you to run a function in a background thread, and then access its return value which is stored in a Future<T>.

Example usage:

Future<int> future = async(calculate_some_int, arg1, arg2); // Trigger the task

while(!future.is_ready()) {}  // Wait while it runs

int result = future.get(); // Get the calculated result

Mutex, SharedMutex, and RecursiveMutex

These mutexes are available in the smlt::thread namespace and in the threads/mutex.h and threads/shared_mutex.h headers.
