[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out of date?
