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 asynchro‐
       nous events will be generated until the event is rearmed.
