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.
