aa_get_pdb(9)

✨ NAME ✨

hey bestie, welcome to aa_get_pdb(9) from the Kernel API Manual 💅 this function is literally here to increment refcount on @pdb — that's the whole vibe, and yes, it's giving “tiny refcount helper with main character energy” ✨

🎀 SYNOPSIS 🎀

struct aa_policydb * aa_get_pdb (struct aa_policydb *pdb );

💖 ARGUMENTS 💖

• pdb — this is the policydb (MAYBE NULL) 🫶 so yes, it can be NULL; the manual literally says MAYBE NULL, no cap.

🦋 RETURN 🦋

• returns a pointer to pdb 🌱
• if pdb is NULL, it will return NULL 😭 so null in, null out, iconic honestly
• Requires: pdb must be held with a valid refcount when called 👑

⚠️ okay bestie, this is the important caveat: pdb must be held with a valid refcount when called. That's a requirement, not a suggestion, fr fr 💀
