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.


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:


       +---------------+-----------------------+
       |ATTRIBUTE TYPE |   ATTRIBUTE VALUE     |
       +---------------+-----------------------+
       |Availability   | network/open-fabrics  |
       +---------------+-----------------------+
       |Stability      | Pass-through volatile |
       +---------------+-----------------------+
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().
