ИМЯ

       ibv_query_srq - get the attributes of a shared receive queue
       (SRQ)

СИНТАКСИС

       #include <infiniband/verbs.h>

       int ibv_query_srq(struct ibv_srq *srq, struct ibv_srq_attr *srq_attr);

ОПИСАНИЕ

       ibv_query_srq() gets the attributes of the SRQ srq and returns
       them through the pointer srq_attr.  The argument srq_attr is an
       ibv_srq_attr struct, as defined in <infiniband/verbs.h>.

       struct ibv_srq_attr {
               uint32_t                max_wr;         /* maximum number of outstanding work requests (WRs) in the SRQ */
               uint32_t                max_sge;        /* maximum number of scatter elements per WR */
               uint32_t                srq_limit;      /* the limit value of the SRQ */
       };

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

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

ПРИМЕЧАНИЯ

       If the value returned for srq_limit is 0, then the SRQ limit
       reached ("low watermark") event is not (or no longer) armed, and
       no asynchronous events will be generated until the event is
       rearmed.
