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(). SEE ALSO

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). SEE ALSO
