parport_find_base(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

parport_find_base β€” bestie, this is literally how you find a parallel port by its base address πŸŽ€

so this is a page from the Kernel API Manual, and it's giving "small function, big responsibility" energy ngl ✨


✨ SYNOPSIS ✨

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 πŸ‘‘


🫢 ARGUMENTS 🫢

  • base β€” the base I/O address. that's the address, bestie. the base one. the starting point. that's your search key πŸ”‘

πŸ”₯ DESCRIPTION πŸ”₯

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 😭 so always check, fr fr.

here's the part where you gotta pay attention, and i mean it πŸ™ˆ 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 πŸ’€

so: find β†’ use β†’ parport_put_port. the holy trinity 🧚
