MEMMOVE(9)

💖 MEMMOVE(9) — copy byte string 💖

okay bestie, welcome to the Kernel Developer's Manual, section 9 — this one is literally about memmove, and it's giving “copy bytes but make it overlap-safe.” 💅✨

🌸 NAME 🌸

memmove — copy byte string. That's the whole vibe, no cap. 💖

✨ SYNOPSIS ✨

#include <sys/systm.h>

void *
memmove(void *dst, const void *src, size_t len);

💅 DESCRIPTION 💅

memmove() copies len bytes from the string src into the string dst, bestie. 🫶

The two strings are allowed to overlap — yep, they can literally be all up in each other's space — and the copy is always done in a non-destructive manner. So it's not here to wreck stuff mid-copy, periodt. 💀✨

🫶 RETURN VALUES 🫶

memmove() returns the original value of dst. That's it. The OG dst, returned right back to you. 🌟

👑 SEE ALSO 👑

🌈 STANDARDS 🌈

memmove() conforms to ANSI X3.159-1989 (“ANSI C89”). Iconic, standardized, slay. 👑
