BN_SWAP(3ossl)

💅 BN_SWAP — exchange BIGNUMs (yes bestie, it's from the 3ossl manual ✨)

Okay so listen. This is the whole entire page for BN_swap, and honestly? It's giving short king. Minimal, iconic, does exactly one thing, does it flawlessly. Let me put you on.

---

🌸 SYNOPSIS 🌸

#include <openssl/bn.h>

void BN_swap(BIGNUM *a, BIGNUM *b);

That's it. That's the whole vibe. Two pointers, zero drama.

---

🦋 DESCRIPTION 🦋

So BN_swap() exchanges the values of a and b.

Like literally, it swaps them. What's in a goes to b, what's in b goes to a. They trade places. Main character energy on both sides, no jealousy, no notes. 💅✨

No cap, this is the entire description. The manpage said what it said and I respect the confidence.

---

🎀 RETURN VALUES 🎀

BN_swap() does not return a value.

It's a void function, bestie — it just does the thing and ghosts. Nothing to check, nothing to compare, no error code to obsess over. Honestly? Queen behavior. 👑
