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.
