fc_exch_timer_set_locked(9)

💅 fc_exch_timer_set_locked(9) 💅

okay bestie, welcome to the Kernel API Manual page for fc_exch_timer_set_locked(9) — yes, the whole page is about starting a timer for an exchange, and it's doing it with the exchange lock held. We love a locked-context moment. 💖

✨ NAME ✨

fc_exch_timer_set_locked — Start a timer for an exchange w/ the the exchange lock held. (the double “the” is literally in the original, no cap 😭)

🌸 SYNOPSIS 🌸

void fc_exch_timer_set_locked (struct fc_exch *ep , unsigned int
       timer_msec );

It returns void, so there's no return value to obsess over — just timer-starting energy. ⏰✨

🎀 ARGUMENTS 🎀

• ep — The exchange whose timer will start. That's the main character exchange right there. 👑
• timer_msec — The timeout period. The name literally says msec, so you already know the unit vibe. ⏱️

🦋 DESCRIPTION 🦋

This one is used for upper level protocols to time out the exchange. The timer is cancelled when it fires or when the exchange completes. That's the whole vibe: set it, and it goes away when it fires or when the exchange is done. 🫶

And yeah — the lock is held, because _locked is right there in the function name and the NAME says “w/ the the exchange lock held.” So this is a locked-context situation, periodt. 🔒💅
