SYNOPSIS

#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 );

DESCRIPTION

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 .

RETURN VALUE

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.

NOTES
