💖 resolve(3z) — z88dk Programmer's Manual 💖

okay bestie, welcome to the z88dk Programmer's Manual ✨ this one's called resolve, and it's here to do one iconic little job: turn a hostname into an IP address. that's it. that's the whole slay. 🦋

---

🌸 NAME 🌸

resolve — convert hostname to IP address 👑

---

✨ SYNOPSIS ✨

#include <net/resolv.h>

ipaddr_t resolve(char *name);

look at that. one include, one function, zero drama. 🎀

---

💅 DESCRIPTION 💅

so like, resolve() goes and queries any configured nameservers for the IP address of the host with the name name. it's giving "who dis, drop the IP". 💌

and if name is already in the form a.b.c.d, then no nameserver needed bestie — it just converts that straight into an IP address and returns it. instant. no cap. 🔥

---

🫶 RETURN VALUE 🫶

resolv() returns the network order IP address of the requested host. 🎯

if the name cannot be resolved, then NULL is returned 😭 and you just have to deal with that emotionally.

also worth knowing: resolv() may also be called by the macro gethostbyname. iykyk 💫

---

💀 BUGS 💀

if you use the macro gethostbyname then beware that the ZSock implementation is not at all standard. not "a little quirky". not "mostly fine". not at all standard. 🙈 proceed with awareness bestie.
