[Boost-users] [asio] Correct handler signature for io_service::post/dispatch

Currently I'm developing a server that uses Boost.Asio, version 1.49. It makes use of io_service::post and io_service::dispatch to invoke handlers running in the same process, but on different threads. Some of the handlers invoke a function with the following signature: void handler(std::string s); This works fine and no problems have been observed. However, subsequently I read in the asio documentation that the function signature of a handler invoked by post/dispatch *must* be in the following format: void handler(); Is my code working by chance or is the asio version 1.49 documentation out of date?
