[Boost-users] [asio] no error or exception sent ?

Hello, i'm using a tcp socket from asio 1.40 framework and i have the following behaviour : i establish a connection to a server and start receiving data i now want my software to be robust to server deconnexion/reset so i simulate it by shuting down the server equipment (which is an external hardware equipement) i would expect such operation to interrupt any pending async_read_some operation with an error code, but it doesn't is there some way to have the expected behaviour ? regards, Mathieu
