alloc_ns(9)

💖 alloc_ns(9) 💖

okay bestie, welcome to the Kernel API Manual page for alloc_ns. This entry is lowkey iconic — it's giving "allocate, initialize and return a new namespace" energy, and we are keeping every detail exactly where it belongs. no cap. ✨

✨ NAME ✨

alloc_ns — does exactly what it says on the tin: allocate, initialize and return a new namespace. periodt. 👑

🦋 SYNOPSIS 🦋

struct aa_ns * alloc_ns (const char *prefix , const char *name );

🎀 ARGUMENTS 🎀

• prefix — parent namespace name (MAYBE NULL). so yeah, it's allowed to be NULL, but only maybe. 👀
• name — a preallocated name (NOT NULL). this one is not optional, bestie — no sneaky NULL name energy here. 🫶

🔥 RETURN 🔥

Hands you back a refcounted namespace, or NULL on failure. slay when it works, NULL when it doesn't. 💅
