💖 gensio_bswap — the Library Functions Manual, but make it cute 💖

okay bestie, this is gensio_bswap(3) from the Library Functions Manual and it's literally just byte swapping, no drama, and honestly? slay. let's get into it 🦋

✨ NAME ✨

gensio_bswap_16, gensio_bswap_32, gensio_bswap_64, GENSIO_IS_BIG_ENDIAN, GENSIO_IS_LITTLE_ENDIAN, gensio_bswap_16_from_be, gensio_bswap_32_from_be, gensio_bswap_64_from_be, gensio_bswap_16_to_be, gensio_bswap_32_to_be, gensio_bswap_64_to_be, gensio_bswap_16_from_le, gensio_bswap_32_from_le, gensio_bswap_64_from_le, gensio_bswap_16_to_le, gensio_bswap_32_to_le, gensio_bswap_64_to_le — Byte swapping routines. periodt. 💅

🌈 SYNOPSIS 🌈

#include <gensio/gensio_byteswap.h>

uint[16|32|64]_t gensio_bswap_[16|32|64](v)

uint[16|32|64]_t gensio_bswap_[16|32|64]_[from|to]_[be|le](v)

🎀 DESCRIPTION 🎀

so these routines do the normal byte swapping thing in 16, 32, and 64-bit values. classic. iconic. no cap.

• gensio_bswap_[16|32|64]() — this one does an unconditional byte swap. it does not care about your host, it does not read the room, it just swaps. main character energy fr fr 🔥
• gensio_bswap_[16|32|64]_[from|to]_[be|le] — these cuties byte swap from/to the given endianness, and the actual swapping that happens depends on your host platform's endianness. iykyk 👑
• GENSIO_IS_BIG_ENDIAN and GENSIO_IS_LITTLE_ENDIAN — these will be true or false depending on the host endian's endianness. yes bestie, the vibes check your machine for you 🫶

⭐ RETURN VALUES ⭐

the integer, byte swapped, will be returned. that's it, that's the whole return value, and honestly it ate 💖
