What are some effective debugging tips for C++ socket programming?

When debugging C++ socket programming, start by checking your socket initialization and error handling. Use tools like gdb for step-by-step execution.

How can I check if my socket is properly connected?

You can use the getsockopt function to check the socket state. Additionally, ensure that you handle the return values of connect properly.

What should I do if my program hangs during a socket operation?

If your program hangs, it might be waiting for a response. Implement timeouts using setsockopt with SO_RCVTIMEO and SO_SNDTIMEO to avoid indefinite blocking.

Are there any common mistakes to avoid in socket programming?

Yes, common mistakes include not closing sockets properly, failing to check for errors after socket calls, and not handling partial sends or receives.
