reset_control_status(9)

✨ reset_control_status(9) ✨

okay so bestie, buckle up — this is a page from the Kernel API Manual and it's lowkey one of the most useful lil vibe checks in the whole reset subsystem 💅

🌸 NAME 🌸

reset_control_status — returns a negative errno if not supported, a positive value if the reset line is asserted, or zero if the reset line is not asserted or if the desc is NULL (optional reset) 🫶

like... it's literally just asking the reset line "hey girl, are you on or off?" and it'll tell you. no cap.

🎀 SYNOPSIS 🎀

int reset_control_status (struct reset_control *rstc );

🦋 ARGUMENTS 🦋

• rstc — reset controller 🌟 (this is the main character of the whole operation, the reset controller you're checking on)

quick reminder bestie: negative errno = not supported 🚫, positive = the reset line is asserted 🔥, zero = it's not asserted or the desc is NULL (that's the optional-reset situation, we love a chill default) 😌

k that's the whole page, mwah 💋
