NAME
ibv_create_cq, ibv_destroy_cq - create or destroy a completion queue (CQ)
SYNOPSIS
#include <infiniband/verbs.h> struct ibv_cq *ibv_create_cq(struct ibv_context *context, int cqe, void *cq_context, struct ibv_comp_channel *channel, int comp_vector); int ibv_destroy_cq(struct ibv_cq *cq);
DESCRIPTION
ibv_create_cq() creates a completion queue (CQ) with at least cqe entries for the RDMA device context context. The pointer cq_context will be used to set user context pointer of the CQ structure. The argument channel is optional; if not NULL, the completion channel channel will be used to return completion events. The CQ will use the completion vector comp_vector for signaling completion events; it must be at least zero and less than context->num_comp_vectors. ibv_destroy_cq() destroys the CQ cq.
RETURN VALUE
ibv_create_cq() returns a pointer to the CQ, or NULL if the request fails. ibv_destroy_cq() returns 0 on success, or the value of errno on failure (which indicates the failure reason).
NOTES
ibv_create_cq() may create a CQ with size greater than or equal to the requested size. Check the cqe attribute in the returned CQ for the actual size. ibv_destroy_cq() fails if any queue pair is still associated with this CQ.
