Question

What are non-fatal errors that accept() can return and how do we handle them ?

Answer 1

The non-fatal errors that the accept() function can return in network programming are related to the network system. They can be handled using error handling mechanisms.

Step-by-step explanation:

The non-fatal errors that the accept() function can return in network programming are mainly related to the underlying network system. Some of these errors include:

1. EAGAIN - The socket is marked non-blocking and no connections are available to be accepted.
2. ECONNABORTED - A connection was aborted.
3. EINTR - The system call was interrupted by a signal before any connections were available.

To handle these errors, the programmer can use error handling mechanisms like error codes or exception handling to gracefully handle the non-fatal errors and continue with the execution of the program.
