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.
