💖 rpma_conn_cfg_get_rcq_size — bestie, let's go get that receive CQ size 💖

✨ NAME ✨

rpma_conn_cfg_get_rcq_size — get the receive CQ size for the connection

---

🌸 SYNOPSIS 🌸

#include <librpma.h>

struct rpma_conn_cfg;
int rpma_conn_cfg_get_rcq_size(const struct rpma_conn_cfg *cfg, uint32_t *rcq_size);

---

🦋 DESCRIPTION 🦋

So rpma_conn_cfg_get_rcq_size() gets the receive CQ size for the connection. That's it. That's the job. 💅

And if you want the actual tea about what the receive CQ even is, bestie, go read rpma_conn_get_rcq() — it has all the details. This function is not gonna explain it to you, it's just gonna hand you the number. 🙈

---

🎀 RETURN VALUE 🎀

rpma_conn_cfg_get_rcq_size() returns 0 on success, or a negative error code on failure. That's the vibe check. ✨

Important, fr fr: if it fails, rpma_conn_cfg_get_rcq_size() does not set the *rcq_size value. So don't go reading that variable like it means something after a failure — it does not. 💀

---

💜 ERRORS 💜

rpma_conn_cfg_get_rcq_size() can fail with this one:

• RPMA_E_INVAL — cfg or rcq_size is NULL. Classic. 😭
