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.
