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 pro- tection 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).
