IBV_RESIZE_CQ(3)        Libibverbs Programmer's Manual        IBV_RESIZE_CQ(3)

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
       guaranteed 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.
