KNET_ADDRTOSTR(3)

KNET_ADDRTOSTR(3) 💖

okay bestie, welcome to the Kronosnet Programmer's Manual — this is the page for knet_addrtostr, and yes it's giving "turn a socket address into something a human can read." slay. 🎀

---

✨ NAME ✨

knet_addrtostr — Convert an address to a host name.

---

✨ SYNOPSIS ✨

#include <libknet.h>

int knet_addrtostr(
    const struct sockaddr_storage   *ss,
    socklen_t                        sslen,
    char                            *addr_buf,
    size_t                           addr_buf_size,
    char                            *port_buf,
    size_t                           port_buf_size
);

✨ DESCRIPTION ✨

knet_addrtostr 🦋

here's the whole vibe, one argument at a time:

• ss — the sockaddr_storage you wanna convert. that's it, that's the one.
• sslen — the len of the sockaddr_storage. length matters, always has 💅
• host — the IPaddr/hostname where to store data. recommended size: KNET_MAX_HOST_LEN. (yes the manpage calls it host here even tho the synopsis says addr_buf, iykyk, they're the same little guy 🫶)
• port — the port buffer where to store data. recommended size: KNET_MAX_PORT_LEN.

no cap, use those recommended sizes. KNET_MAX_HOST_LEN and KNET_MAX_PORT_LEN exist for a reason and the reason is you not overflowing a buffer. 😭

---

✨ RETURN VALUE ✨

ok so <cyan>knet_strtoaddr</cyan> returns the same error codes as getnameinfo. (yes bb, the page literally says knet_strtoaddr in the return value section. we are not editing the lore. 📜✨)
