πŸ¦‹ parport_ip32_fifo_wait_break(9) β€” the Kernel API Manual bestie edition πŸ¦‹

okay so this is a page from the Kernel API Manual, and it's lowkey one of the most useful little gremlins in the parport_ip32 family. no cap. let's get into it πŸ’…


✨ NAME ✨

parport_ip32_fifo_wait_break β€” the vibe check that tells the waiting function whether it should bail out and return already πŸ’€


🌸 SYNOPSIS 🌸

unsigned int parport_ip32_fifo_wait_break (struct parport *p , unsigned long expire );

it returns an unsigned int, and it takes the two cuties listed below, bestie 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • p β€” pointer to struct parport. literally just your parport, handing over its address so we can peek at it 🌈
  • expire β€” the timeout expiring date, in jiffies ⏰ (yes, jiffies, the kernel's own little unit of time. iconic.)

πŸ‘‘ DESCRIPTION πŸ‘‘

parport_ip32_fifo_wait_break checks if the waiting function should return immediately or not. that's the whole job. it's giving "are we done here or no" energy πŸ”₯

the break conditions β€” aka the reasons to dip out early β€” are:

  • expired timeout ⏰
  • a pending signal πŸ“Ά
  • nFault asserted low ⚠️

also, this function calls cond_resched. yep, that too β€” it's part of the package, no extra charge πŸ’–


πŸ’œ SEE ALSO πŸ’œ
