parse_lease_state(9)

💅 parse_lease_state(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is page parse_lease_state(9) and it's literally about one job: digging a lease context out of a file open request. That's it. That's the whole vibe. 🎀

---

🌸 NAME 🌸

parse_lease_state — parse lease context contained in file open request

like... the name is the plot, no cap 💖

---

✨ SYNOPSIS ✨

struct lease_ctx_info * parse_lease_state (void *open_req );

yes she's a function that returns a pointer to a struct lease_ctx_info *, and yes she takes exactly one thing. iconic signature honestly 👑

---

🦋 ARGUMENTS 🦋

• open_req — the buffer containing the smb2 file open(create) request 🔥 this is the raw request blob you're handing over, and it's a void * so... bestie, be normal about what you pass in 🫶

---

💜 RETURN 💜

on success you get the newly allocated lease context object — yay, memory, congrats, that thing is yours now 🎀

otherwise? NULL. that's the whole story. no object, no party 😭

quick reminder bestie: the return value being NULL on failure is not a drill — treat it like a vibe check and handle it 🙈
