πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… find_pa_parent_type β€” the kernel page, but make it make sense

okay so this is a page from the Kernel API Manual (9), and it's literally about finding your fave's parent. no cap. let's get into it πŸŽ€


✨ NAME ✨

find_pa_parent_type β€” find a parent of a specific type 🫢

like, you have a device, you want its ancestor that matches a certain type. that's the whole vibe.


🌸 SYNOPSIS 🌸

const struct parisc_device * find_pa_parent_type (const struct parisc_device *padev , int type );

that's it. two args in, a const struct parisc_device * out. iconic signature honestly πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • padev β€” the device you start searching from. your main character. everything kicks off here ✨
  • type β€” the device type you're hunting for. the vibe check you're running every ancestor against πŸ”₯

πŸ’– DESCRIPTION πŸ’–

so it walks up the device tree 🌈 β€” like, going from your girl upward through her ancestors β€” looking for a device of the specified type. if it finds one, it returns it. if it doesn't? it returns NULL. 😭 nothing. no match. empty-handed. it's giving "no thoughts, head empty."

no cap, that's the entire behaviour. walk up, match the type, return it or return NULL. periodt. πŸ‘‘
