irdma_send_cm_event(9) 💅

okay so this one's from the Kernel API Manual (yes, the kernel has a manual, and yes it's lowkey iconic) and it's basically about upcalls — like when the CM layer needs to yell upstairs to the event handler, this is the lil function that carries the message. 🎀

✨ NAME ✨

irdma_send_cm_event — the upcall to cm's event handler, fr fr. It's the one knocking on the upper layer's door like "bestie, something happened, here's the tea." ☕

🌸 SYNOPSIS 🌸

int irdma_send_cm_event (struct irdma_cm_node *cm_node , struct iw_cm_id
*cm_id , enum iw_cm_event_type type , int status );

she takes four arguments and returns an int, no cap 🫶

🦋 ARGUMENTS 🦋

  • cm_node — the connection's node 🧚 that's the CM-side record of the connection we're talking about, main character energy.
  • cm_id — the upper layer's cm info struct 💖 like, the other layer's little info packet for the same connection. mutuals.
  • type — the event type to indicate 🔥 which flavour of "something happened" we're announcing.
  • status — the status for the event type 🌈 the vibes report that comes along with the event, bestie.
ngl, that's the whole argument list — short and slay. four args, zero notes. periodt. 💅
