NAME
ibv_init_ah_from_wc, ibv_create_ah_from_wc - initialize or create an
address handle (AH) from a work completion
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
The filled structure
ah_attr
returned from
ibv_init_ah_from_wc()
can be used to create a new AH using
ibv_create_ah().
