void no arguments
Description
Asynchronous events are reported to users through event channels.
Name
rdma_create_event_channel - Open a channel used to report communication events.
Notes
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.
Return Value
Returns a pointer to the created event channel, or NULL if the request fails. On failure, errno will be
set to indicate the failure reason.
