dml21_create(9)

💅 dml21_create(9) — from the Kernel API Manual, bestie

okay so picture this: you're a kernel dev, you need a dml21_context, and this little cutie is the function that makes it happen. it's giving "birth of a context" energy fr fr. ✨

---

🌸 NAME 🌸

dml21_create — literally creates a dml21_context. that's it, that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

bool dml21_create (const struct dc *in_dc , struct dml2_context
**dml_ctx , const struct dml2_configuration_options *config );

no cap, that's the whole signature — copy it exactly, don't get cute with it. 👑

---

💖 ARGUMENTS 💖

• in_dc — the dc. yes that's the entire description, she's a woman of few words and we respect it. 🙈
• dml_ctx — the freshly created dml21 context. this is the output, the main character, the one you came for. ⭐
• config — the dml21 configuration options. the settings, the preferences, the lewk. 💅

---

🔥 DESCRIPTION 🔥

so the creation of DML21 goes down as part of dc_state creation — like, they're a package deal, you don't get one without the other. 🫶

and the moment it's created, DML21 IP, SOC and STATES all get initialized right then and there. first breath, first init, iconic behavior only. ✨

🌈 RETURN 🌈

• true — dml2 got successfully created, slay, we love to see it 💜
• false — it did not. 😭

💀 reminder: false is a real possible answer, so please actually check the return value before you go dereferencing anything. no cap.
