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(). ibv_open_device (3), ibv_alloc_pd (3), ibv_create_ah (3), ibv_destroy_ah (3), ibv_poll_cq (3)
