dns_name4(3)

NAME 💖

okay bestie, this is the dns_name4(3) page from the Library Functions Manual — and it's all about dns_name4, the function that does one job: look up host name. iconic behavior, honestly. 🎀

SYNTAX <✨>

#include <libowfat/dns.h>

int dns_name4(stralloc* out,const char* ip[4]);

DESCRIPTION <💅>

okay so here's the tea: dns_name4 is gonna look up the domain name for the 4-byte IP address sitting in ip. Then it drops the (first) domain name into out and returns 0. slay. ✨

But if the relevant in-addr.arpa domain does not exist in DNS, or has no PTR records, then out will be empty. no cap. 😭

If dns_name4 has trouble with the DNS lookup or runs out of memory, it returns -1, setting errno appropriately. also important: it may or may not change out. so don't assume, bestie. 💀
