qbman_result_SCN_ctx(9)

💅 qbman_result_SCN_ctx 💅

okay so bestie, welcome to the Kernel API Manual page for qbman_result_SCN_ctx — section 9 of the manual, if you're keeping track. this one's a little baby function and honestly? she's giving "understood by three people and they all work at NXP" energy. let's get into it 🎀

---

✨ NAME ✨

qbman_result_SCN_ctx — grab the context data out of a State-change notification. that's it. that's the whole gig. no cap 🫶

---

🌸 SYNOPSIS 🌸

u64 qbman_result_SCN_ctx (const struct dpaa2_dq *scn );

literally copy that exactly, don't @ me. returns a u64, takes a pointer to a const struct dpaa2_dq named scn. iconic signature, no notes ✨

---

🦋 ARGUMENTS 🦋

• scn — okay so the official documentation for this one is, and I cannot stress this enough, literally -- undescribed -- 😭💀 like the manpage itself is out here with a blank bio. that's the whole entry. so: it's a const struct dpaa2_dq *, it's your state-change notification, and the docs are not gonna hold your hand any further than that. main character energy of a function to just not describe its own parameter, honestly. i respect it and i'm also screaming 🙈
