RDMA_ACK_CM_EVENT(3)

💖 rdma_ack_cm_event — free a communication event 💖

okay bestie, welcome to the librdmacm programmer's manual ✨ this one is short and sweet, which is honestly a vibe, because it means you have zero excuse not to get it right. it's giving "tiny function, huge consequences." 🎀

✨ SYNOPSIS ✨

#include <rdma/rdma_cma.h>

int rdma_ack_cm_event (struct rdma_cm_event *event);

🌸 ARGUMENTS 🌸

• event — the event you're releasing. like, letting it go. freeing it. saying bye. 🦋

💅 DESCRIPTION 💅

okay so here's the tea. every single event that gets allocated by rdma_get_cm_event must be released. all of them. no skipping. 🫶

and the way that it works is there should be a one-to-one correspondence between successful gets and acks. one get, one ack. one get, one ack. it's a matching set, it's a couple, it's a duo, do not leave one hanging. 💀

this call frees the event structure and any memory that it references. so yes, it's doing the whole thing. the struct, the stuff inside the struct, all of it. gone. iconic. ✨

⭐ RETURN VALUE ⭐

• returns 0 on success 👑
• returns -1 on error 😭

and if an error happens, errno will be set to indicate the failure reason. so like, check it. please. for me. 🙈

🌈 SEE ALSO 🌈

• rdma_get_cm_event(3)
• rdma_destroy_id(3)

no cap: gets and acks go together. mismatched pairs are not the vibe. 🚫
