💖 GETNODEADD — Library Functions Manual 💖

okay bestie, so getnodeadd is a little GETNODEADD(3) moment from the Library Functions Manual and she is so much simpler than she sounds. let's get into it 🦋

✨ NAME ✨

getnodeadd — the DECnet address of the executor node 👑

🌸 SYNOPSIS 🌸

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

struct dn_naddr *getnodeadd (void)

like. that's it. no arguments, no drama, she just takes nothing and gives you a pointer. main character energy fr 💅

🎀 DESCRIPTION 🎀

so what she does is: getnodeadd goes digging through the decnet hosts file looking for the executor node, and when she finds it she hands you back the DECnet address inside a dn_naddr structure. 🫶

and if there's no entry to be found? she returns NULL. no entry, no vibes, no address. periodt.

🌈 EXAMPLE 🌈

here's the whole thing in action, literally copy-paste coded for you:

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

main(void)
{
    struct dn_naddr          *binaddr;

    if ( (binaddr=getnodeadd()) == NULL)
        printf("Error, cannot find executor node address");
    else
        printf("getnodeadd successfully got executor node address");
}

see how it's giving? if the pointer comes back NULL you print "Error, cannot find executor node address", and if she actually found something you print "getnodeadd successfully got executor node address". ate. 🔥
