rdma_resolve_route man page
rdma_resolve_route — Resolve the route information needed to establish a connection.
int rdma_resolve_route (struct rdma_cm_id *id, int timeout_ms);
Time to wait for resolution to complete.
Resolves an RDMA route to the destination address in order to establish a connection. The destination address must have already been resolved by calling rdma_resolve_addr.
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason.
This is called on the client side of a connection after calling rdma_resolve_addr, but before calling rdma_connect.
This call obtains a path record that is used by the connection.
