UUID_COPY(3)

💖 UUID_COPY(3) — like, the copy-paste moment for UUIDs 💖

okay so before we even start: this is a page from the Programmers Manual, section 3 (that's the library-functions girlies ✨). and bestie, this one is short — it's giving "one job, does it well, leaves" and honestly? respect. 🫶

✨ NAME ✨

uuid_copy — copy a UUID value. that's it. that's the whole gig. 💅

---

✨ SYNOPSIS ✨

#include <uuid.h>

void uuid_copy(uuid_t dst, const uuid_t src);

so you gotta pull in <uuid.h> first — no header, no vibes. 📚

---

✨ DESCRIPTION ✨

the uuid_copy() function copies the UUID variable src to dst. 🎀

that's literally it, no cap. one UUID goes in, the same UUID comes out the other side, dst is now that girl. it's the most low-key iconic function in the whole library — no parsing, no generating, no drama, just a handoff. 🦋

---

✨ RETURN VALUE ✨

plot twist: it doesn't return anything (it's void, she's mysterious like that 💀). instead, the copied UUID is returned in the location pointed to by dst. so like, look at dst, that's where your prize is. 👑
