✨ SSL_CTX_has_client_custom_ext 💅

okay bestie, welcome to the 3ossl girlies — this is an OpenSSL manual page and honestly? it's a short one. a lil baby page. a snack. and you're gonna understand it in like twelve seconds. let's go 🎀

NAME 🦋

SSL_CTX_has_client_custom_ext — check whether a handler exists for a particular client extension type

that's it. that's the whole job. it's a vibe check for extension handlers. no cap. ✨

SYNOPSIS 🌸

#include <openssl/ssl.h>

int SSL_CTX_has_client_custom_ext(const SSL_CTX *ctx, unsigned int ext_type);

look at her. two args. returns an int. she's lowkey perfect. 👑

DESCRIPTION 💖

so, SSL_CTX_has_client_custom_ext() literally just checks whether a handler has been set for a client extension of type ext_type using SSL_CTX_add_client_custom_ext().

like. that's the whole thing. you hand it a context and an extension type, and it tells you if somebody already registered a handler for that type. it's giving "did anyone sign up for this?" energy. 🙈

it does NOT add a handler. it does NOT remove one. it does NOT call one. it just looks. pure observation. main character behavior honestly. 🦋

RETURN VALUES ⭐

  • Returns 1 if a handler has been set ✨
  • Returns 0 otherwise 💀

binary queen. she said "yes or no and I will not be elaborating." periodt. 💅
