,
use the dispatch

free functions.
For example:
void my_task() { ... } ... // Launch the pool with four threads. asio::thread_pool pool(4); // Submit a function to the pool. asio::post(pool, my_task); // Submit a lambda object to the pool. asio::post(pool, []() { ... }); // Wait for all tasks in the pool to complete. pool.join();
