💖 getnetbyname — z88dk Programmer's Manual 💖

okay bestie, welcome to the z88dk manual, this one's all about network entries and honestly it's short and sweet, we love a low-effort slay ✨

---

🌸 NAME 🌸

getnetbyname, getnetbynumber — get network entry

like, that's the whole job. you want a network entry? girl, these two got you 🫶

---

✨ SYNOPSIS ✨

#include <net/resolv.h>

int getnetbyname(char *name);
char *getnetbynumber(int network, char * buf);

---

🦋 DESCRIPTION 🦋

okay so first up, getnetbyname() — you hand it a network name, and it hands you back the standard number for that network. cute, right? but bestie, listen: if no network is known, you get NULL back. not a number, not a sad little zero, just NULL. so check it. 😭

then there's getnetbynumber() — this one takes network and copies the matching network into buf, and yes it also returns buf because it's generous like that 💅. but plot twist: if no network is known, then network itself gets returned, in ASCII form. so like, you asked for a thing and you got the number you typed back as text. it's giving "we don't know her" energy fr fr.

👑 RETURN VALUE 👑

detailed above, bestie. scroll up, it's all there, no cap 🌈

---

🎀 NOTES 🎀

these functions use a lookup table compiled into the ZSock kernel, and ngl it is not likely that method will change in the near future. so like, the vibe is stable, iykyk 🧚
