int ibv_destroy_srq(struct ibv_srq *srq);int ibv_destroy_srq(struct ibv_srq *srq); Description ibv_destroy_srq() destroys a Shared Receive Queue. The destruction of a Shared Receive Queue will fail if any QP is still associated with it. If there is any affiliated asynchronous event on that...
struct ibv_srq *ibv_create_srq(struct ibv_pd *pd, struct ibv_srq_init_attr *srq_init_attr);struct ibv_srq *ibv_create_srq(struct ibv_pd *pd, struct ibv_srq_init_attr *srq_init_attr); Description ibv_create_srq() creates a Shared Receive Queue (SRQ) associated with a Protection Domain. This SRQ will later be used when calling ibv_create_qp() to indicate that...
int ibv_resize_cq(struct ibv_cq *cq, int cqe);int ibv_resize_cq(struct ibv_cq *cq, int cqe); Description ibv_resize_cq() resizes a Completion Queue. A CQ can be resized either if it is empty or contains Work Completions that still weren’t polled by ibv_poll_cq(). It can be...
