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). ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+-----------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+-----------------------+ |Availability | network/open-fabrics | +---------------+-----------------------+ |Stability | Pass-through volatile | +---------------+-----------------------+ 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.
