💅 nbd_get_opt_mode — the libnbd girlie's guide 💅

okay so bestie, you're in the libnbd zone right now, specifically the <libnbd.h> part of town, and this page is all about nbd_get_opt_mode(3). it's giving "tiny function, big feelings". let's go ✨

🌸 NAME 🌸

nbd_get_opt_mode — returns whether option mode was enabled, no cap, that's literally the whole job 🫶

🎀 SYNOPSIS 🎀

get your #include in first, always:

#include <libnbd.h>

and then the function itself, looking all cute and minimal:

int nbd_get_opt_mode (
      struct nbd_handle *h
    );

🦋 DESCRIPTION 🦋

so this one's simple and i'm obsessed: it returns true if option negotiation mode was enabled on this handle h. that's it. that's the tweet. ✨

⭐ RETURN VALUE ⭐

this call returns a boolean value. true or false, that's the whole vibe check. 🎀

💀 ERRORS 💀

good news bestie: this function does not fail. not me being flawless 😭 no error codes, no drama, we love a low-maintenance icon.

but listen — the following parameters must not be NULL: "h". for more info, see "Non-NULL parameters" in libnbd(3). don't be the person who passes NULL, i'm begging 🙈

🔥 VERSION 🔥

this function first appeared in libnbd 1.4 — vintage, honestly, a classic 👑

if you need to test if this function is available at compile time, check if the following macro is defined:

#define LIBNBD_HAVE_NBD_GET_OPT_MODE 1
