NAME

       rdma_create_event_channel - Open a channel used to report communication events.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       struct rdma_event_channel * rdma_create_event_channel (void);

ARGUMENTS

       void        no arguments

DESCRIPTION

       Asynchronous events are reported to users through event channels.

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.

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.
