💅 SSL_SESSION_is_resumable — the OpenSSL manual page (yes bestie, we're reading a manpage, and it's from the 3ossl section, slay)

Okay so picture this: you've got an SSL_SESSION object just sitting there, looking all cute and mysterious, and you need to know the one thing that matters — can this thing actually be reused? That's literally the whole page. Let's get into it 🔥

✨ NAME ✨

SSL_SESSION_is_resumable — determine whether an SSL_SESSION object can be used for resumption 🎀

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

int SSL_SESSION_is_resumable(const SSL_SESSION *s);

✨ DESCRIPTION ✨

Bestie, listen. SSL_SESSION_is_resumable() determines whether an SSL_SESSION object can be used to resume a session or not. That's the whole job description. Returns 1 if it can, or 0 if it can't. Iconic, simple, no drama 💅

⚠️ Heads up though — attempting to resume with a non-resumable session will result in a full handshake. Not me warning you before you waste a whole handshake on the wrong session 😭

✨ RETURN VALUES ✨

SSL_SESSION_is_resumable() returns 1 if the session is resumable or 0 otherwise. That's it, that's the return section, she's brief and she ate 🌸
