C++ application: Is it possible to pass accepted TCP connection from one process to another?

Question

So I wonder - is it possible to pass accepted TCP connection (on Windows or Unix like OS) from one process to another? Here the point is to pass connection - not data in a w

Answer 1

In Unix, a TCP connection is represented as a socket file descriptor. When you fork a process, the file descriptors are inherited by the child process, including TCP sockets. (Though they may be closed on exec if given the FD_CLOEXEC flag with fcntl.)

It's also possible to transfer file descriptors between unrelated processes using a local (Unix) domain socket; see this question.

I'm not sure about Windows.
