💖 gnutls_dtls_get_data_mtu 💖

okay bestie, welcome to the gnutls manual, section 3 — we're deep in the library call girlies today. this one lives in the gnutls docs and it's called gnutls_dtls_get_data_mtu, and yes she's an API function, no cap. 🎀

✨ NAME ✨

gnutls_dtls_get_data_mtu — API function. that's it, that's the name, she's serving exactly what it says on the tin. 💅

🌸 SYNOPSIS 🌸

#include <gnutls/dtls.h>

unsigned int gnutls_dtls_get_data_mtu(gnutls_session_t session);

literally the whole vibe. include the header, call the function, get your number back. 🦋

🎀 ARGUMENTS 🎀

  • gnutls_session_t session — bestie this is a gnutls_session_t type. that's the whole personality. your session, your girl, your context. she knows things. 🫶

💜 DESCRIPTION 💜

okay so here's the tea. this function returns the actual maximum transfer unit for application data. and "actual" is doing WORK in that sentence, because it's not just handing you whatever MTU you set — no ma'am. it takes the MTU you configured with gnutls_dtls_set_mtu() and it subtracts the DTLS headers from it. ✨

so what you're getting back is the real, usable, app-data-only budget. the header tax has already been paid. it's giving honest numbers only. 💅

⭐ RETURNS ⭐

the maximum allowed transfer unit. that's the whole return value, she's concise and she's correct. 🔥

🌈 SINCE 🌈

3.0 — she's been here since 3.0, an absolute icon, a veteran, main character energy since day one. 👑

🙈 REPORTING BUGS 🙈

found something cursed? not me manifesting bugs, but if it happens:

fr fr, tell them. they want to know. 🍓
