rdma_getaddrinfo - Provides transport independent address translation.
int rdma_getaddrinfo (char *node, char *service, struct rdma_addrinfo
*hints, struct rdma_addrinfo **res);
node Optional, name, dotted-decimal IPv4, or IPv6 hex address to
service Service name or port number of address.
hints Reference to an rdma_addrinfo structure containing hints
about the type of service the caller supports.
res A pointer to a linked list of rdma_addrinfo structures
containing response information.
Resolves the destination node and service address and returns
information needed to establish communication. Provides the RDMA
functional equivalent to getaddrinfo.
Returns 0 on success, or -1 on error. If an error occurs, errno will
be set to indicate the failure reason.
Either node or service must be provided. If hints are provided, the
operation will be controlled by hints.ai_flags. If RAI_PASSIVE is
specified, the call will resolve address information for use on the
passive side of a connection.
ai_flags Hint flags that control the operation. Supported flags
RAI_PASSIVE Indicates that the results will be used on the
passive/listening side of a connection.
If specified, then the node parameter, if provided, must be
a numerical network address. This flag suppresses any
lengthy address resolution.
RAI_NOROUTE If set, this flag suppresses any lengthy route resolution.
ai_family Address family for the source and destination address.
Supported families are: AF_INET, AF_INET6, and AF_IB.
ai_qp_type Indicates the type of RDMA QP used for communication.
Supported types are: IBV_UD (unreliable datagram) and
IBV_RC (reliable connected).
RDMA port space in use. Supported values are: RDMA_PS_UDP
ai_src_len The length of the source address referenced by ai_src_addr.
This will be 0 if an appropriate source address could not
be discovered for a given destination.
ai_dst_len The length of the destination address referenced by
ai_dst_addr. This will be 0 if the RAI_PASSIVE flag was
specified as part of the hints.
ai_src_addr If provided, the address for the local RDMA device.
ai_dst_addr If provided, the address for the destination RDMA device.
The canonical for the source.
The canonical for the destination.
Size of the routing information buffer referenced by
ai_route. This will be 0 if the underlying transport does
not require routing data, or none could be resolved.
ai_route Routing information for RDMA transports that require
routing data as part of connection establishment. The
format of the routing data depends on the underlying
transport. If Infiniband transports are used, ai_route
will reference an array of struct ibv_path_data.
Size of connection information referenced by ai_connect.
This will be 0 if the underlying transport does not require
additional connection information.
ai_connect Data exchanged as part of the connection establishment
process. If provided, ai_connect data must be transferred
as private data, with any user supplied private data
ai_next Pointer to the next rdma_addrinfo structure in the list.
Will be NULL if no more structures exist.
