dc_commit_streams(9)

💅 dc_commit_streams(9) — like, the Kernel API Manual, but make it cute

okay so bestie, welcome to the dc_commit_streams page from the Kernel API Manual ✨ this one's short and sweet but she's important — she's the one who actually pushes your stream changes down into the hardware, no cap 🫶

---

✨ NAME ✨

dc_commit_streams — commit current stream state 🎀

---

🌸 SYNOPSIS 🌸

enum dc_status dc_commit_streams (struct dc *dc , struct
dc_commit_streams_params *params );

like, that's the whole vibe. two args. she's lowkey elegant 💅

---

🦋 ARGUMENTS 🦋

• dc — the DC object, aka the one holding the commit state that's getting configured in the hardware 👑
• params — the parameters for the commit, and yes that includes the streams that are getting committed 🍓

---

💖 DESCRIPTION 💖

this is the function responsible for committing stream changes to the hardware. that's it, that's the whole description — she ate and left no crumbs 😭

---

🌈 RETURN 🌈

returns DC_OK if everything works as expected ✨ otherwise it hands you back a dc_status code instead 🙈 so like, always check her, okay?

bestie pls actually look at the return value, that's the whole point of the return value 💀
