RDMA_CREATE_QP(3)

NAME
rdma_create_qp - Allocate a QP.

SYNOPSIS
#include <rdma/rdma_cma.h>

int rdma_create_qp (struct rdma_cm_id *id, struct ibv_pd *pd, struct ibv_qp_init_attr *qp_init_attr);

ARGUMENTS

id  RDMA identifier.

pd  protection domain for the QP.

qp_init_attr
    initial QP attributes.

DESCRIPTION
Allocate a QP associated with the specified rdma_cm_id and transition it for sending and receiving.

NOTES
The rdma_cm_id must be bound to a local RDMA device before calling this function, and the protection domain must be for that same device. QPs allocated to an rdma_cm_id are automatically transitioned by the librdmacm through their states. After being allocated, the QP will be ready to handle posting of receives. If the QP is unconnected, it will be ready to post sends.
