ssh_rtl_submit(9)

💅 ssh_rtl_submit(9) — like, the Kernel API Manual, but make it make sense 🫶

okay bestie, so this one lives in the Kernel API Manual and it's called ssh_rtl_submit(9). it's the "hey, send this thing out" function, and honestly it's giving short-and-sweet main character energy. let's get into it ✨

---

🌸 NAME 🌸

ssh_rtl_submit — submit a request to the transport layer. that's it, that's the vibe. 💅

---

✨ SYNOPSIS ✨

int ssh_rtl_submit (struct ssh_rtl *rtl , struct ssh_request *rqst );

like, you hand it a transport layer and a request, and it returns an int. simple. iconic. no notes. 💜

---

🎀 ARGUMENTS 🎀

• rtl — the request transport layer. this is the ~infrastructure~, the pipeline, the whole thing the request travels through. lowkey important ngl.
• rqst — the request to submit. the actual payload. the star of the show. 👑

---

🦋 DESCRIPTION 🦋

so what it does is literally: submits a request to the transport layer. that's the whole job. it's not doing a little extra on the side, it's not "oh let me also" — no, it submits and it's done. periodt. 🔥

the big caveat, and please internalize this bestie: a single request may not be submitted multiple times without reinitializing it. like, one request, one submission. if you want to send it again you gotta reinit it first. no cap. 🙈

---

💀 RETURN 💀

what you get back, and what it means, fr fr:

• 0 — success! it worked, slay, congrats, you ate. 🎉
• -EINVAL — the request type is invalid or the request has been canceled prior to submission. bad input vibes, or you canceled too hard. 😭
• -EALREADY — the request has already been submitted. bestie. you already did this one. we talked about this. 💀
• -ESHUTDOWN — the request transport layer has been shut down. the whole thing is closed, nothing's home, sorry babe. 🚪
