I’ve been working on a simple example with a Julia server and a C client communicating over a UNIX domain socket. If I call `shutdown(my_socket, SHUT_RDWR)` from the C client, then calling `isopen(my_socket)` in Julia returns `false`, as expected. But if I do try to have the Julia server shutdown the socket by calling `close(my_socket)`, the C client’s pending `recv` call doesn’t return with an error, it just continues to block.

Does `close(my_socket)` not shutdown the socket in a way the client can see? Is there an equivalent to C’s `shutdown` in Julia?

Thank you for the help!

I had an error in my Julia server - it was blocking trying to read more bytes than the client had sent. So it was never even closing the socket. With that fixed, my C client’s extra `recv` call does receive 0 bytes, as expected.
