💅 tb_port_alloc_in_hopid — the Kernel API Manual, bestie edition 🎀

okay so real talk, this is a page from the Kernel API Manual (tb_port_alloc_in_hopid(9)) and it's literally about getting yourself an input HopID off a port. tiny page, but it eats. let's go ✨

🌸 NAME 🌸

tb_port_alloc_in_hopid — allocate an input HopID from a port 🫶

✨ SYNOPSIS ✨

int tb_port_alloc_in_hopid (struct tb_port *port , int min_hopid , int
max_hopid );

like, that's the whole vibe check right there 💅

💖 ARGUMENTS 💖

  • port — the port you're allocating the HopID for, bestie 🎀
  • min_hopid — the minimum acceptable input HopID, like your floor, your bare minimum, no cap
  • max_hopid — the maximum acceptable input HopID, aka the ceiling, the limit, the "don't push it" line 👑

⭐ RETURN ⭐

you get a HopID between min_hopid and max_hopid — slay — or a negative errno if something goes wrong 😭 that's it, that's the deal, periodt.
