DNET_HTOA(3)

💖 DNET_HTOA — ok bestie, let's talk 💖

soooo this is dnet_htoa(3), a lil library function from the Library Functions Manual, and honestly? it's giving translator energy. it takes a DECnet address and goes "oh hey, that's a node, and its name is…" 🦋

✨ NAME ✨

dnet_htoa — DECnet address to host name translation. that's it, that's the job, no cap 💅

✨ SYNOPSIS ✨

#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>

char *dnet_htoa (struct dn_naddr *addr)

✨ DESCRIPTION ✨

ok so dnet_htoa goes and searches the decnet hosts file for addr, and then hands you back the DECnet node name. iconic behaviour fr fr 🌸

and if it doesn't find an entry? no drama, no crash — it just returns the ascii DECnet address in the format area.node (like 1.1, 1.2, etc). lowkey a fallback queen 👑

✨ EXAMPLE ✨

here's the whole thing in action, verbatim, don't touch it 🎀

#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>
#include <sys/socket.h>

main(void)
{
    struct dn_naddr          binaddr;

    binaddr.a_len  = 2;
    binaddr.a_addr[0]   = 0x02;
    binaddr.a_addr[1]   = 0x04;

    printf ("DECnet node name is %s",dnet_htoa(binaddr));

}

like. she's setting up a struct dn_naddr, a_len is 2, a_addr[0] is 0x02, a_addr[1] is 0x04, and then boom — printf prints the node name. main character energy tbh ⭐
