GNUTLS_TRANSPORT_SET_PULL_FUNCTION(3)

💖 gnutls_transport_set_pull_function — API function 💖

okay bestie, welcome to the gnutls manual, you're gonna eat this up ✨

---

🌸 NAME 🌸

gnutls_transport_set_pull_function — it's an API function, bestie. that's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

#include <gnutls/gnutls.h>

void gnutls_transport_set_pull_function(gnutls_session_t session,
gnutls_pull_func pull_func);

---

🦋 ARGUMENTS 🦋

• gnutls_session_t session — this one is a gnutls_session_t type. that's it, that's the whole description, no cap 🫶
• gnutls_pull_func pull_func — a callback function that's giving major read() energy, iykyk 😌

---

✨ DESCRIPTION ✨

so like, this is the function where you set a function for gnutls to receive data. 🧚

ngl, if you're using berkeley style sockets, you do not need to use this function, because the default recv(2) will probably be ok. like, it just works, bestie. 💅

but if you <em>do</em> write your own callback, here's the tea on what it has to return:

• 0 — connection termination, we're done here 😭
• a positive number — that's the number of bytes received, slay 👑
• -1 — error. it's giving tragedy 💀

and here's the shape of gnutls_pull_func, exactly as written, no edits:

ssize_t
(*gnutls_pull_func)(gnutls_transport_ptr_t, void*, size_t);

periodt. 💖
