ARGUMENTS

DESCRIPTION
       Return a NULL-terminated array of opened RDMA devices.  Callers can use
       this routine to allocate resources on specific RDMA devices  that  will
       be shared across multiple rdma_cm_id's.

RETURN VALUE

       fails.  On failure, errno will be set to indicate the failure reason.
