       ibv_modify_cq - modify a completion queue (CQ)

SYNOPSIS

       #include <infiniband/verbs.h>

       int ibv_modify_cq(struct ibv_cq *cq, struct ibv_modify_cq_attr *cq_attr);

DESCRIPTION

       ibv_modify_cq()  modify a CQ cq.  The argument cq_attr is an ibv_modify_cq_attr struct, as
       defined in <infiniband/verbs.h>.

       struct ibv_moderate_cq {
               uint16_t cq_count;  /* number of completions per event */
               uint16_t cq_period; /* in micro seconds */
       };

       struct ibv_modify_cq_attr {
                    uint32_t attr_mask;
                    struct ibv_moderate_cq moderate;
       };

       The function ibv_modify_cq() will modify the CQ, based on the given cq_attr->attr_mask

RETURN VALUE

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