💅 DH_GET_EX_NEW_INDEX(3) 💅

okay okay, welcome to the Library Functions Manual corner of the group chat, bestie 🫶 this one is short but it’s literally the whole vibe: adding application specific data to DH structures ✨

🎀 NAME 🎀

• DH_get_ex_new_index, DH_set_ex_data, DH_get_ex_data — the little trio that adds application specific data to DH structures 💅

---

✨ SYNOPSIS ✨

first up, this lives in the libcrypto library, no cap:

library “libcrypto” #include <openssl/dh.h>

int
DH_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func,
    CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func);

int
DH_set_ex_data(DH *d, int idx, void *arg);

char *
DH_get_ex_data(DH *d, int idx);

---

🌸 DESCRIPTION 🌸

These functions handle application specific data in DH structures. That’s the whole assignment, and they ate 💖

Their usage is identical to that of RSA_get_ex_new_index(3), RSA_set_ex_data(3), and RSA_get_ex_data(3) — like, same energy, same rules, periodt 🌈

🦋 SEE ALSO 🦋

• DH_new(3)
• RSA_get_ex_new_index(3)

👑 HISTORY 👑

DH_get_ex_new_index(), DH_set_ex_data(), and DH_get_ex_data() first appeared in OpenSSL 0.9.5 and have been available since OpenBSD 2.7 ⭐
