RDMA_DEST...T_CHANNEL(3)

💖 RDMA_DEST...T_CHANNEL 💖

okay bestie, so this is a page from the Librdmacm Programmer's Manual and it's literally about closing an event communication channel. it's giving "cleanup era". no cap.

✨ NAME ✨

rdma_destroy_event_channel — close an event communication channel. that's it, that's the whole job. she's a closer. 💅

🌸 SYNOPSIS 🌸

#include <rdma/rdma_cma.h>

void rdma_destroy_event_channel (struct rdma_event_channel *channel);

so you pull in <rdma/rdma_cma.h> and then you call her. she returns nothing, she takes one thing. simple. iconic. 🎀

🦋 ARGUMENTS 🦋

• channel — the communication channel you wanna destroy. yes, the actual one. the one you made earlier. we're saying bye to her. 🫶

💜 DESCRIPTION 💜

okay so what this function does is release all resources associated with an event channel, and it also closes the associated file descriptor. that's the whole vibe. you hand her the channel, she frees the stuff, she closes the fd, everybody goes home. lowkey the most satisfying part of any program, ngl. 😭✨

🌈 RETURN VALUE 🌈

None. she returns nothing. not void-ish "check me", not an error code, nothing. None. periodt. 💀

⭐ NOTES ⭐

bestie listen. this is the important part and I need you locked in. 🚨

before you call this function, you have to make sure:

• all rdma_cm_id's associated with the event channel are destroyed first, and
• all returned events have been acked.

that's a must-must, not a should. do it in the wrong order and it's not gonna be cute. 🙈
