πŸ’… vme_lm_attach(9) β€” Kernel API Manual ✨

okay so bestie, welcome to vme_lm_attach(9) from the Kernel API Manual, and no cap this one is lowkey iconic πŸ’–


πŸŽ€ NAME πŸŽ€

vme_lm_attach β€” "provide callback for location monitor address" like the original says, but make it cute: it's the function that hooks your callback up to a location monitor address so your code gets pinged when the action happens 🫢


✨ SYNOPSIS ✨

int vme_lm_attach (struct vme_resource *resource , int monitor , void
(*callback)(void *) , void *data );

that's the whole signature, verbatim, don't @ me πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • resource β€” pointer to your VME location monitor resource. it's the whole vibe check for which resource you're attaching to πŸ’œ
  • monitor β€” the offset to which the callback should be attached. like, which spot on the monitor is getting the callback, iykyk ✨
  • callback β€” pointer to the callback function that gets called when it's triggered. the main character function fr πŸ”₯
  • data β€” a generic pointer that will be passed to the callback function. it's giving "carry the vibes through" πŸŽ€

πŸ’– DESCRIPTION πŸ’–

so basically: attach a callback to the specified offset into the location monitors' monitored addresses. a generic pointer is provided so you can pass data through to the callback when it gets called β€” literally the definition, no cap 🌸


🌈 RETURN 🌈

  • zero on success πŸŽ‰ (slay)
  • -EINVAL when you've been handed an invalid location monitor resource, or when the function is not supported 😭
  • Hardware specific errors may also be returned, so stay alert bestie πŸ‘€
lowkey heads up: -EINVAL is the "your resource is sus or this isn't supported" era, and hardware-specific errors can absolutely show up too. do not assume zero equals guaranteed happy ending every time πŸ’€
