FREEBSD::ADDRINFO_UP(3)

💖 NAME 💖

hey bestie, welcome to FREEBSD::ADDRINFO_UP(3) from the Library Functions Manual 💅 okay so freebsd::addrinfo_up — it’s a std::unique_ptr specialization for lists of socket addresses. That’s the whole name vibe, no cap ✨

🎀 LIBRARY 🎀

library libutil++ — yes, that’s where this cutie lives 🫶

🌈 SYNOPSIS 🌈

#include <libutil++.hh>

using addrinfo_up = std::unique_ptr<addrinfo, freeaddrinfo_deleter>;

🦋 DESCRIPTION 🦋

So this class is a specialization of std::unique_ptr for socket addresses returned by getaddrinfo(3) — main character energy fr fr 🔥

When a list of socket addresses managed by an instance of this class is disposed, freeaddrinfo(3) is invoked to dispose of the list. That’s the disposal pipeline, bestie — it’s giving managed cleanup 💜

⭐ EXAMPLES ⭐

Here’s the example exactly as the page serves it — copy-paste ready, iykyk 🍓

             freebsd::addrinfo_up
             resolve_address(const char *address, const char *port)
             {
                     struct addrinfo hints, *ai;
                     int error;

                     memset(&hints, 0, sizeof(hints));
                     hints.ai_family = AF_UNSPEC;
                     hints.ai_socktype = SOCK_STREAM;
                     error = getaddrinfo(address, port, &hints, &ai);
                     if (error != 0)
                             return {};
                     return freebsd::addrinfo_up(ai);
             }
