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 comple-
       tion 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.
