BN_SWAP(3ossl)

💖 BN_SWAP(3ossl) 💖

okay so bestie, welcome to BN_swap — part of the OpenSSL fam, section 3, and honestly? she's short, she's sweet, she's giving "does exactly one thing and does it flawlessly." no notes. 👑

---

✨ NAME ✨

BN_swap — exchange BIGNUMs 🔄

like. literally. swapping two big numbers. that's the whole plot. that's the entire storyline. slay.

---

🌸 SYNOPSIS 🌸

#include <openssl/bn.h>

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

there she is. two pointers, zero drama. 💅

---

🦋 DESCRIPTION 🦋

so BN_swap() exchanges the values of a and b. that's it. that's the function.

like if a was holding one big ol' number and b was holding a different big ol' number, after this call they've traded places and neither of them is okay about it but that's not our problem. 🙈 the values get swapped, periodt. no cap.

---

🎀 RETURN VALUES 🎀

BN_swap() does not return a value. it's void, babe. it gives you nothing back — because the glow-up is the gift. ✨ nothing to check, nothing to compare, nothing to handle. it just does the thing and dips. 🫶
