NAME

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

SYNOPSIS

       #include <infiniband/verbs.h>

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

DESCRIPTION

       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 */
       };

RETURN VALUE

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

NOTES

       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.
