ibv_init_ah_from_wc, ibv_create_ah_from_wc - initialize or create an
address handle (AH) from a work completion
#include <infiniband/verbs.h>
int ibv_init_ah_from_wc(struct ibv_context *context, uint8_t port_num,
struct ibv_wc *wc, struct ibv_grh *grh,
struct ibv_ah_attr *ah_attr);
struct ibv_ah *ibv_create_ah_from_wc(struct ibv_pd *pd,
struct ibv_wc *wc,
struct ibv_grh *grh,
uint8_t port_num);
ibv_init_ah_from_wc() initializes the address handle (AH) attribute
structure ah_attr for the RDMA device context context using the port
number port_num, using attributes from the work completion wc and the
Global Routing Header (GRH) structure grh.
ibv_create_ah_from_wc() creates an AH associated with the protection
domain pd using the port number port_num, using attributes from the
work completion wc and the Global Routing Header (GRH) structure grh.
ibv_init_ah_from_wc() returns 0 on success, and -1 on error.
ibv_create_ah_from_wc() returns a pointer to the created AH, or NULL
if the request fails.
The filled structure ah_attr returned from ibv_init_ah_from_wc() can
be used to create a new AH using ibv_create_ah().
