swap_buf_le16(9)

✨ swap_buf_le16(9) ✨

okay bestie, you're in the Kernel API Manual and this is the entry for swap_buf_le16 — tiny endian helper, extremely focused, lowkey iconic. 💅

🌸 NAME 🌸

swap_buf_le16 — swap halves of 16-bit words in place.

🛠️ SYNOPSIS 🛠️

void swap_buf_le16 (u16 *buf , unsigned int buf_words );

🎀 ARGUMENTS 🎀

• buf — Buffer to swap. That's the buffer getting its word-halves flipped, bestie. 🫶
• buf_words — Number of 16-bit words in buffer. Count the 16-bit words, not vibes. ✨

💖 DESCRIPTION 💖

Swap halves of 16-bit words if needed to convert from little-endian byte order to native cpu byte order, or vice-versa.

It's literally a byte-order glow-up: the function swaps the halves of the 16-bit words when that's what's needed for the little-endian ↔ native cpu conversion. No cap. 🔥

LOCKING: Inherited from caller. So the caller brought the locking energy; this function did not come with its own. 💀
