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().
