ishtp_cl_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the ishtp_cl_link(9) girlies 😌 this one lives in the Kernel API Manual, and honestly? she's a tiny function with main character energy. let's get into it 🎀

✨ NAME ✨

ishtp_cl_link — reserve a host id and link the client instance 🫶

🌸 SYNOPSIS 🌸

int ishtp_cl_link (struct ishtp_cl *cl );

that's it. that's the whole vibe check. 💅

🦋 ARGUMENTS 🦋

  • cl — the client device instance 💜 like, the actual client thing you're linking up, no cap

⭐ DESCRIPTION ⭐

okay so here's what's happening under the hood, and it's lowkey cute:

this function allocates a single bit in the hostmap ✨ that's the whole bit-allocation moment, she's very demure about it.

and the way that it's also doing crowd control?? 😭 this function will make sure that not many client sessions are opened at the same time — like she's the friend at the door going "okay we're at capacity bestie, no more people in the Uber." iconic behavior fr fr.

once that bit is allocated, the client device instance gets added to the ishtp device in the current client list 🌈 so now she's officially on the list. she's in. she belongs. 🫶

🔥 RETURN 🔥

returns 0 or an error code on failure 💀 (so like, check it, don't just assume she slayed)
