I am not in a position to call async_read, as it will read out some valuable data (if the connection is not closed). Al least is there any "dirty way" to do this?

Inside the timer handler routine, is there any way to chek the connection is closed or> not? (From the timer handler, I can access the socket and io_service). Not really. To detect peer disconnection you can perform an async_readon that socket, and in most cases it will call its handler with someerror. But this method doesn't always work - eg., in case of a"non-graceful" cable disconnection._______________________________________________Boost-users mailing listBoost-users@lists.boost.orghttp://lists.boost.org/mailman/listinfo.cgi/boost-users
