parport_ip32...o_wait_break(9)
π¦ parport_ip32_fifo_wait_break(9) β the Kernel API Manual bestie edition π¦
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 π
β¨ NAME β¨
parport_ip32_fifo_wait_break β the vibe check that tells the waiting function whether it should bail out and return already π
πΈ SYNOPSIS πΈ
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 π«Ά
π ARGUMENTS π
pβ pointer tostruct parport. literally just your parport, handing over its address so we can peek at it πexpireβ the timeout expiring date, in jiffies β° (yes, jiffies, the kernel's own little unit of time. iconic.)
π DESCRIPTION π
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 π₯
the break conditions β aka the reasons to dip out early β are:
- expired timeout β°
- a pending signal πΆ
nFaultasserted low β οΈ
also, this function calls cond_resched. yep, that too β it's part of the package, no extra charge π
