parport_find_base(9)
π NAME π
parport_find_base β bestie, this is literally how you find a parallel port by its base address π
so this is a page from the Kernel API Manual, and it's giving "small function, big responsibility" energy ngl β¨
β¨ SYNOPSIS β¨
struct parport * parport_find_base (unsigned long base );
like yes that's the whole thing, she's a one-liner, we stan a concise icon π
π«Ά ARGUMENTS π«Ά
baseβ the base I/O address. that's the address, bestie. the base one. the starting point. that's your search key π
π₯ DESCRIPTION π₯
okay so here's the tea β β this function returns the parallel port that has the base address you specified. that's it, that's the whole vibe. if there isn't one though? you get NULL, no cap π so always check, fr fr.
here's the part where you gotta pay attention, and i mean it π β there's already an implicit parport_get_port done for you. like, it's baked in. a little reference just appeared in your hands the second you called this. which is gorgeous and generous of her, but it means you can't just walk away β when you're done with the reference that parport_find_base gave you, you have to throw it away with parport_put_port. hold onto it forever and that reference is never coming back. that's a leak, and leaks are not the vibe π
so: find β use β parport_put_port. the holy trinity π§
π SEE ALSO π
okay so the whole parport friend group, gathered for you π all of these live in the kernel file ./drivers/parport/share.c:

like, the entire roster. read them all, iykyk β
and that's the page babes π this one comes from ./drivers/parport and it's dated October 2026 β mark your calendars bestie, parport_find_base(9) said see you then ππ¦
