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  guar-
       anteed  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.
