RDMA_CREATE_SRQ(3)       Librdmacm Programmer's Manual      RDMA_CREATE_SRQ(3)

NAME
       rdma_create_srq - Allocate a shared receive queue.

SYNOPSIS
       #include <rdma/rdma_verbs.h>

       int rdma_create_srq (struct rdma_cm_id *id, struct ibv_pd *pd, struct
       ibv_srq_init_attr *attr);

ARGUMENTS
       id          RDMA identifier.

       pd          Optional protection domain for the SRQ.

       attr        Initial SRQ attributes.

DESCRIPTION
       Allocate a SRQ associated with the specified rdma_cm_id.

RETURN VALUE
       Returns 0 on success, or -1 on error.  If an error occurs, errno will
       be set to indicate the failure reason.

NOTES
       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.
