nbd_get_strict_mode(3)

✨ nbd_get_strict_mode(3) ✨

okay so this is a page from the libnbd manual and honestly it's a little sleeper hit — it's the one that tells you which protocol strictness vibes are currently being enforced. let's get into it 🎀

---

💖 NAME 💖

nbd_get_strict_mode — see which strictness flags are in effect. that's it, that's the whole thing, and it's lowkey important 🫶

---

🌸 SYNOPSIS 🌸

#include <libnbd.h>

uint32_t nbd_get_strict_mode (
           struct nbd_handle *h
         );

bestie, it's a getter. one handle in, one uint32_t out. no drama 💅

---

🦋 DESCRIPTION 🦋

so what this does is return flags indicating which protocol strictness items are being enforced locally by libnbd rather than by the server. like, these are the rules your own library is out here policing by itself, no server input needed, main character energy fr fr 👑

one thing to keep in mind (and this is a real one, not a drill): the return value from a newer library version may include bits that were undefined at the time of compilation. so if you built against an older header and then run against a newer lib, you might see bits you've literally never heard of. that's expected, not a bug — don't panic 😭

---

⭐ RETURN VALUE ⭐

This call returns a bitmask of LIBNBD_STRICT_* values. bitmask, so you're gonna be doing bitwise checks — you know the drill ✨

---

🔥 ERRORS 🔥

This function does not fail. no cap, it literally cannot fail. it's giving unbothered, it's giving flawless 🌈

The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in libnbd(3). so like, don't hand it a null handle, that's the one thing 🫠

---

🧚 VERSION 🧚

This function first appeared in libnbd 1.6.

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_STRICT_MODE 1

iykyk — that macro is your little vibe check for compile time 💫
