RDMA_RESOLVE_ADDR(3) Librdmacm Programmer's Manual RDMA_RESOLVE_ADDR(3)
rdma_resolve_addr - Resolve destination and optional source
addresses.
#include <rdma/rdma_cma.h>
int rdma_resolve_addr (struct rdma_cm_id *id, struct sockaddr
*src_addr, struct sockaddr *dst_addr, int timeout_ms);
id RDMA identifier.
src_addr Source address information. This parameter may be
NULL.
dst_addr Destination address information.
timeout_ms Time to wait for resolution to complete.
Resolve destination and optional source addresses from IP
addresses to an RDMA address. If successful, the specified
rdma_cm_id will be bound to a local device.
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
This call is used to map a given destination IP address to a
usable RDMA address. The IP to RDMA address mapping is done using
the local routing tables, or via ARP. If a source address is
given, the rdma_cm_id is bound to that address, the same as if
rdma_bind_addr were called. If no source address is given, and
the rdma_cm_id has not yet been bound to a device, then the
rdma_cm_id will be bound to a source address based on the local
routing tables. After this call, the rdma_cm_id will be bound to
an RDMA device. This call is typically made from the active side
of a connection before calling rdma_resolve_route and
rdma_connect.
This call maps the destination and, if given, source IP addresses
to GIDs. In order to perform the mapping, IPoIB must be running
on both the local and remote nodes.
