NAME
       ibv_resize_cq - resize a completion queue (CQ)

SYNOPSIS
       #include <infiniband/verbs.h>

       int ibv_resize_cq(struct ibv_cq *cq, int cqe);

DESCRIPTION
       ibv_resize_cq()	resizes the completion queue (CQ) cq to have at least cqe entries.  cqe must be at least the number of unpolled entries in
       the CQ cq.  If cqe is a valid value less than the current CQ size, ibv_resize_cq() may not do anything, since this function is only guaran-
       teed to resize the CQ to a size at least as big as the requested size.

RETURN VALUE
       ibv_resize_cq() returns 0 on success, or the value of errno on failure (which indicates the failure reason).

NOTES
       ibv_resize_cq() may assign a CQ size greater than or equal to the requested size.  The cqe member of cq will be updated to the actual size.
