mux_state_deselect(9)

okay so welcome to the Kernel API Manual, bestie 💖 this is the page for mux_state_deselect(9), aka the “okay we’re done with that mux state now” icon. Grab a lil snack 🍓 and let’s go.

💖 NAME 💖

mux_state_deselect — Deselect the previously selected multiplexer state.

✨ SYNOPSIS ✨

int mux_state_deselect (struct mux_state *mstate );

🎀 ARGUMENTS 🎀

• mstate — The mux-state to deselect. That’s the one, bestie.

🦋 DESCRIPTION 🦋

okay so the rule is literally: a single call to mux_state_deselect is required for each and every successful call made to either mux_state_select or mux_state_try_select. No cap. If a select succeeds, its matching deselect has to show up exactly once. It’s giving “pair your socks” energy 🧦✨

bestie the pairing is not optional — one successful select/try-select = one mux_state_deselect call.

🔥 RETURN 🔥

0 on success, and a negative errno on error. An error can only occur if the mux has an idle state. And even if an error occurs, the mux-control is unlocked and is thus free for the next access — so it’s not gonna ghost the next caller, periodt. 💅
