RDMA_CREATE_SRQ(3) Librdmacm Programmer's Manual RDMA_CREATE_SRQ(3)
rdma_create_srq - Allocate a shared receive queue.
#include <rdma/rdma_verbs.h>
int rdma_create_srq (struct rdma_cm_id *id, struct ibv_pd *pd,
struct ibv_srq_init_attr *attr);
id RDMA identifier.
pd Optional protection ___domain for the SRQ.
attr Initial SRQ attributes.
Allocate a SRQ associated with the specified rdma_cm_id.
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
The rdma_cm_id must be bound to a local RDMA device before calling
this function, and the protection ___domain, if provided, must be for
that same device. After being allocated, the SRQ will be ready to
handle posting of receives.
If a protection ___domain is not given - pd parameter is NULL - then
the rdma_cm_id will be created using a default protection ___domain.
One default protection ___domain is allocated per RDMA device.
The initial SRQ attributes are specified by the attr parameter.
The ext.xrc.cq fields in the ibv_srq_init_attr is optional. If a
completion queue is not specified for an XRC SRQ, then a CQ will
be allocated by the rdma_cm for the SRQ, along with corresponding
completion channels. Completion channels and CQ data created by
the rdma_cm are exposed to the user through the rdma_cm_id
structure.
The actual capabilities and properties of the created SRQ will be
returned to the user through the attr parameter. An rdma_cm_id
may only be associated with a single SRQ.
