int rdma_resolve_route (struct rdma_cm_id *id, int timeout_ms);



RDMA identifier.


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.

Return Value

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.

Infiniband Specific

This call obtains a path record that is used by the connection.
