nbd_get_tls_hostname(3)

okay bestie, welcome to nbd_get_tls_hostname(3) from the LIBNBD manual set 💖 this one is short and sweet, no cap.

✨ NAME ✨

nbd_get_tls_hostname — get the effective TLS hostname 🎀

🌸 SYNOPSIS 🌸

        #include <libnbd.h>

        char * nbd_get_tls_hostname (
                 struct nbd_handle *h
               );

So you include <libnbd.h> and call it with a struct nbd_handle *h. Slay.

💅 DESCRIPTION 💅

Get the TLS server hostname that’s actually in effect. If it hasn’t been set, bestie, this returns the empty string — and that is not an error. It’s giving “no hostname set, no problem” energy 🦋.

🫶 RETURN VALUE 🫶

This call returns a string. The caller must free the returned string to avoid a memory leak. Like, literally free it. Your future self will thank you 😭.

😭 ERRORS 😭

• On error NULL is returned.
• Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.
• The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in libnbd(3).

⭐ VERSION ⭐

This function first appeared in libnbd 1.22.
