💖 rpma_conn_get_qp_num 💖

okay bestie, welcome to the RPMA Programmer's Manual ✨ we're doing a lil deep dive on rpma_conn_get_qp_num and honestly? it's giving "small function, big main character energy" 🫶

🌸 NAME 🌸

---

int rpma_conn_get_qp_num(const struct rpma_conn *conn, uint32_t *qp_num);

---

🦋 DESCRIPTION 🦋

so like. rpma_conn_get_qp_num() obtains the unique identifier of the connection. that's it, that's the whole job, and it ate 💅 it just hands you the one-of-a-kind lil number that says "this connection? yeah, THIS one." periodt 👑

---

🎀 RETURN VALUE 🎀

the rpma_conn_get_qp_num() function returns 0 on success, or a negative error code on failure 😭

and hear me out, this part matters: rpma_conn_get_qp_num() does not set *qp_num value on failure. so like, don't go reading that thing like it's gospel when things went sideways, bestie 🚫

---

💀 ERRORS 💀

rpma_conn_get_qp_num() can fail with the following error:

• RPMA_E_INVAL — conn or qp_num is NULL 🙈 (yeah, one of your pointers ghosted you)
