Trf_FlipRegisterLong(3)

💅 Trf_FlipRegisterLong — bestie edition

okay so. this is a manual page for Trf_FlipRegisterLong(3), which lives in the Library Functions Manual, and it does exactly one thing but it does it iconically. if you're the kind of person who needs to byte-swap a whole buffer of 4-byte words, this is your girl. no cap. 🦋

✨ NAME ✨

Trf_FlipRegisterLong — swap the bytes of all 4-byte words contained in the buffer.

that's it. that's the whole personality. she flips. she swaps. she goes home. 💅

🌸 SYNOPSIS 🌸

#include <transform.h>

void Trf_FlipRegisterLong
(
     void *buffer,
     int length
);

so you pull in transform.h, and then you call the function with a buffer and a length. returns void, meaning she gives you nothing back except the satisfaction of a job well done. honestly? main character energy. ✨

🎀 PARAMETERS 🎀

• void *buffer — the data to swap. this is your little pile of bytes and she's about to rearrange them. be normal about it. 🙈
• int length — length of buffer, and yes bestie it's in byte. not in words, not in vibes, in bytes. 🍓

👑 DESCRIPTION 👑

Swap the bytes of all 4-byte words contained in the buffer.

like. okay. imagine your buffer is a bunch of 4-byte words sitting there in a row, and each one has its bytes in the wrong order (endianness, we've all been there 😭). this function goes through and flips every single one of those 4-byte words so the bytes come out the other way around. every word. all of them. she does not skip. she does not miss. she's that girl. 💖

ngl this is the kind of thing you want to be very sure you actually need before you call it, because she will absolutely rearrange your data with zero hesitation. 🌈

🔥 SEE ALSO 🔥

she does not exist in a vacuum, bestie, she's part of a whole family of Trf functions and they're all connected. go read up:

and yeah, Trf_FlipRegisterShort(3) is her shorter sibling. same energy, half the bytes. 🫶

and that's the whole page, bestie!! this cutie came out of c2man transform.h and it's dated 27 August 2002 — yes, she's an elder but she still slays. mwah. 💋✨🎀
