us_socket_context_connect timeout about usockets HOT 6 OPEN

We don't provide any timeout. That timeout comes from the OS. You control the timeout in your OS, or use us_socket_timeout on the connecting socket.

Thank you. I think that to use us_socket_timeout the us_socket_context_connect has to finish first. The problem I am facing is to control the timeout for the connect. Do you know how to change the OS timeout?

You don't need to wait. us_socket_context_connect returns a us_socket_t and you can start a timeout directly when it returns. The only thing that can take time inside us_socket_context_connect is if you pass it some domain name that doesn't resolve immediately. But you can solve that by resolving the domain to an IP yourself, before you call us_socket_context_connect.

I am passing a local IP address and port that is not assigned to any device on purpose to try to limit the timeout and it takes 20s to return the socket. Is there a way to make the us_socket_context_connect to exit from another thread?

from usockets.

us_socket_context_connect calls some hostname resolving syscall that hangs until done. So you cannot abort it. Just make sure whatever you pass us_socket_context_connect actually resolves to something and it should return immediately. You can do this by resolving whatever you want to connect to before you pass it to us_socket_context_connect.

Thank you, I will do that.
As I am passing the IP address I think the hostname resolution could be bypassed.
If you could point out what function the hostname resolution I could locally patch it.
Perhaps it could be also addressed later as an improvement to the library.
