💅 tee_shm_is_dynamic(9) — the vibe check for dynamic shared memory

Okay bestie, welcome to the Kernel API Manual ✨ — yes that's the whole manual name, we're not doing the giant header banner today, we're just vibing straight into the good stuff.

---

🌸 NAME

tee_shm_is_dynamic — lowkey just checks whether a shared memory object is the dynamic kind 🫶

So like, if you ever find yourself holding a struct tee_shm * and wondering "is this one of the dynamic ones or not", this is literally the function for you. No cap.

---

🎀 SYNOPSIS

bool tee_shm_is_dynamic (struct tee_shm *shm );

Yep that's it. One argument, returns a bool, done. She's simple, she's iconic, she minds her own business 💖

---

🦋 ARGUMENTS

• shm — shared memory handle 🧚 the actual struct tee_shm pointer you're asking about. Hand it over and let the function do its little investigation.

---

⭐ RETURN

Returns true if the object is dynamic shared memory — that's the whole answer, bestie. If it's dynamic, true; if it's not, well, not true. The hedges are doing the work, we don't make claims the source doesn't make 🔥

No ERR_PTR shenanigans, no negative returns, just a clean little boolean truth-telling moment 👑
