✨ gnutls_dtls_get_mtu(3) ✨

okay bestie, welcome to the gnutls manual, section 3 (that's library functions, iykyk) 💅 this one's a lil baby page and it's literally just about asking a DTLS session "hey girl, what MTU did we set?" — short, sweet, iconic 🎀

🌸 NAME 🌸

gnutls_dtls_get_mtu — the API function, the moment, the legend ✨

🦋 SYNOPSIS 🦋

#include <gnutls/dtls.h>

unsigned int gnutls_dtls_get_mtu(gnutls_session_t session);

💖 ARGUMENTS 💖

  • gnutls_session_t session — bestie. it's a gnutls_session_t type. that's the whole vibe. that's the whole argument. she's the session you're interrogating 🫶

👑 DESCRIPTION 👑

so what does this do? it returns the MTU size as set with gnutls_dtls_set_mtu(). that's it. that's the function. it hands you back the number you (or somebody) already told it.

and now the part where you need to pay attention, no cap: this is NOT the actual MTU of data you can transmit. it's just the set value, not the real usable amount. if you want the actual data MTU, you gotta use gnutls_dtls_get_data_mtu() instead. don't mix these up, that's the whole plot twist 💀

⭐ RETURNS ⭐

the set maximum transfer unit. that's it. she delivers ✨

🌈 SINCE 🌈

3.0 — been serving looks since 3.0, a true OG 👑
