       ibv_create_srq, ibv_destroy_srq - create or destroy a shared receive queue (SRQ)

       #include <infiniband/verbs.h>

       struct ibv_srq *ibv_create_srq(struct ibv_pd *pd, struct
				      ibv_srq_init_attr *srq_init_attr);

       int ibv_destroy_srq(struct ibv_srq *srq);

       ibv_create_srq()  creates  a  shared  receive  queue  (SRQ) associated with the protection
       domain pd.  The argument srq_init_attr is  an  ibv_srq_init_attr  struct,  as  defined  in

       struct ibv_srq_init_attr {
	       void		      *srq_context;    /* Associated context of the SRQ */
	       struct ibv_srq_attr     attr;	       /* SRQ attributes */

       struct ibv_srq_attr {
	       uint32_t 	       max_wr;	       /* Requested max number of outstanding work requests (WRs) in the SRQ */
	       uint32_t 	       max_sge;        /* Requested max number of scatter elements per WR */
	       uint32_t 	       srq_limit;      /* The limit value of the SRQ (irrelevant for ibv_create_srq) */

       The  function ibv_create_srq() will update the srq_init_attr struct with the original val-
       ues of the SRQ that was created; the values of max_wr and max_sge will be greater than  or
       equal to the values requested.

       ibv_destroy_srq() destroys the SRQ srq.

       ibv_create_srq() returns a pointer to the created SRQ, or NULL if the request fails.

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

       ibv_destroy_srq() fails if any queue pair is still associated with this SRQ.
