IBV_CREATE_AH(3)					  Libibverbs Programmer's Manual					  IBV_CREATE_AH(3)

NAME

       ibv_create_ah, ibv_destroy_ah - create or destroy an address handle (AH)

SYNOPSIS

       #include <infiniband/verbs.h>

       struct ibv_ah *ibv_create_ah(struct ibv_pd *pd,
				    struct ibv_ah_attr *attr);

       int ibv_destroy_ah(struct ibv_ah *ah);

DESCRIPTION

       ibv_create_ah()	creates  an  address handle (AH) associated with the protection domain pd.  The argument attr is an ibv_ah_attr struct, as
       defined in <infiniband/verbs.h>.

       struct ibv_ah_attr {
	       struct ibv_global_route grh;	       /* Global Routing Header (GRH) attributes */
	       uint16_t 	       dlid;	       /* Destination LID */
	       uint8_t		       sl;	       /* Service Level */
	       uint8_t		       src_path_bits;  /* Source path bits */
	       uint8_t		       static_rate;    /* Maximum static rate */
	       uint8_t		       is_global;      /* GRH attributes are valid */
	       uint8_t		       port_num;       /* Physical port number */
       };

       struct ibv_global_route {
	       union ibv_gid	       dgid;	       /* Destination GID or MGID */
	       uint32_t 	       flow_label;     /* Flow label */
	       uint8_t		       sgid_index;     /* Source GID index */
	       uint8_t		       hop_limit;      /* Hop limit */
	       uint8_t		       traffic_class;  /* Traffic class */
       };

       ibv_destroy_ah() destroys the AH ah.

RETURN VALUE

       ibv_create_ah() returns a pointer to the created AH, or NULL if the request fails.

       ibv_destroy_ah() returns 0 on success, or the value of errno on failure (which indicates the failure reason).
