🦋 DESCRIPTION 🦋

okay so real talk, this function has no big difference from gaokun_ec_read — they're basically twins, fr fr 👯

but here's the ~moment~: when the caller cares only about write status and no actual data are returned, then use it. that's the whole thing. that's the assignment. periodt 💅

so like, if you're sitting there waiting for a payload to come back, wrong function bestie 🙈 this one's just here to tell you if the write went okay.

🔥 RETURN 🔥

• 0 on success 🎉
• negative error code if it went sideways 😭 (not zero, not "meh" — negative, ngl that's how you know)
