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.
