🎀 NAME 🎀

rdma_init_qp_attr — returns qp attributes of an rdma_cm_id. literally that’s the main-character job 💖

🦋 SYNOPSIS 🦋

              #include <rdma/rdma_cma.h>

              int rdma_init_qp_attr(struct rdma_cm_id *id,
                             struct ibv_qp_attr *qp_attr,
                             int *qp_attr_mask);

🌸 DESCRIPTION 🌸

so rdma_init_qp_attr() returns qp attributes of an rdma_cm_id — yes bestie, it’s giving “get me the qp attrs” energy 💅

the tea about qp attributes and the qp attributes mask comes back to you through the qp_attr and qp_attr_mask parameters. that’s the whole handoff 🫶

for the full details on the qp_attr structure, go look at ibv_modify_qp — that’s where the lore lives, iykyk ⭐

💜 ARGUMENTS 💜

• id — the RDMA identifier. like, the main character of this call 👑
• qp_attr — a reference to a qp attributes struct containing response information. it’s bringing the response info back to you 🎀
• qp_attr_mask — a reference to a qp attributes mask containing response information. also carrying response info, but make it mask ✨

🔥 RETURN VALUE 🔥

rdma_init_qp_attr() returns 0 on success, or -1 on error. if an error occurs, errno will be set to indicate the failure reason — so you know why, bestie 😭
