Re: [Boost-users] Suggestion about using Signals2

Just one last thing..

I've tried to to something like this (where signal_OnData is a signal):

void SerialPort::reading() {  .... data available...  //signal_OnData();  _io.post( boost::bind(&SerialPort::Post_OnData, this) ); }

void SerialPort::Post_OnData() {  signal_OnData(); };

but the SerialPort::Post_OnData is not called, is this my design wrong?

I guess that your io_service is not running, so noone processes its queue. You have to call io_service::run function, it's kindof "message loop" of io_service: http://www.boost.org/doc/libs/1_38_0/doc/html/boost_asio/tutorial/tutdaytime...
