Hi Igor,I have a situation where at termination of my program, I am closing my socket, and then deleting the socket object. Note, we are using non-asynchronous (blocking) accesses at this point, boost is version 1.36. In some cases, the socket has had some data written to it, but that data is never received by the connected client - because I destroy the socket before the data is sent. So, SO_LINGER is the socket option that is supposed to solve all my worries (it should wait on close for any unsent data to be sent), however I am using it and there is no effect. I presume because I'm doing something wrong.SO_LINGER is just forwarded as-is to the native socket API, so if it doesn't work there's some problem with the socket. What I couldn't understand from your description is whether you used sync. or async. i/o, and from what thread (same as close() or some other). Could you please clarify these points?
