yup, that's the whole signature. one arg, int coming back at u. no cap ✨

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function tries to make a free PEB by means of synchronous execution of pending works. read that again. synchronous. she's not waiting around for some background thread to get to it, she's doing it herself, right now, in front of everyone. main character energy fr fr 👑

and ngl, this may be needed if, for example, the background thread is disabled 😭 like when the usual worker is off duty and somebody still needs a free PEB, this is the girl u call. mmmhm. we love a reliable icon.

returns zero in case of success and a negative error code in case of failure. so like, zero is the slay outcome, negative is the "oop" outcome. check ur return values bestie, always 🫶
