NUTSCAN_CIDR_TO_IP(3)

💖 NUTSCAN_CIDR_TO_IP 💖

okay bestie, so this is a page from the NUT Manual — yes, that's the Network UPS Tools manual, and the function we're stanning today is nutscan_cidr_to_ip, living its best life over in section 3 of the manual (that's the library-functions section, iykyk). 🎀

---

✨ NAME ✨

nutscan_cidr_to_ip — convert a CIDR IP to a range of IP address. 💅

---

✨ SYNOPSIS ✨

#include <nut-scan.h>

int nutscan_cidr_to_ip(const char * cidr, char ** start_ip, char ** stop_ip);

---

✨ DESCRIPTION ✨

so the way that nutscan_cidr_to_ip() works is literally iconic: you hand it a range of IP address written in CIDR format as a string in cidr, and it gives you back two IPs as strings — pointed to by start_ip and stop_ip 🦋 — and those two lil cuties can be used as input parameters in the scanning functions of the libnutscan API. no cap. 🔥

⚠️ bestie listen — it is the caller's responsibility to free(3) the start_ip and stop_ip strings. like, that's on you. don't be the girl who leaks memory, we are not doing that in this house 🙈

---

✨ RETURN VALUE ✨

nutscan_cidr_to_ip() returns 0 if an error occurred (invalid cidr address) 😭 or 1 if successful ✨. that's it, that's the vibe check. two outcomes, no in-between. 💀

---

✨ NOTES ✨

technically 🧚 the function is currently defined in nutscan-ip.h file. not the file you'd guess from the vibe, but okay, slay, we move. 👑
