Примечание (Note)

Event channels are used to direct all events on an rdma_cm_id.
       For many clients, a single event channel may be sufficient,
       however, when managing a large number of connections or cm_id's,
       users may find it useful to direct events for different cm_id's
       to different channels for processing.

       All created event channels must be destroyed by calling
       rdma_destroy_event_channel.  Users should call rdma_get_cm_event
       to retrieve events on an event channel.

       Each event channel is mapped to a file descriptor.  The
       associated file descriptor can be used and manipulated like any
       other fd to change its behavior.  Users may make the fd non-
       blocking, poll or select the fd, etc.
