IBV_QUERY_SRQ(3)        Libibverbs Programmer's Manual        IBV_QUERY_SRQ(3)

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.
