Overview
The explain_getaddrinfo_or_die function is used to call the getaddrinfo(3) system call. On failure, an explanation will be printed to stderr, obtained from explain_getaddrinfo(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_getaddrinfo_or_die(node, service, hints, res);- node
-
The node, exactly as to be passed to the getaddrinfo(3) system call.
- service
-
The service, exactly as to be passed to the getaddrinfo(3) system call.
- hints
-
The hints, exactly as to be passed to the getaddrinfo(3) system call.
- res
-
The res, exactly as to be passed to the getaddrinfo(3) system call.
- Returns:
-
This function only returns on success. On failure, prints an explanation and exits.
