ИМЯ

       rdma_create_event_channel - Open a channel used to report
       communication events.

СИНТАКСИС

       #include <rdma/rdma_cma.h>

       struct rdma_event_channel * rdma_create_event_channel (void);

АРГУМЕНТЫ

       void        no arguments

ОПИСАНИЕ

       Asynchronous events are reported to users through event channels.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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.

ПРИМЕЧАНИЯ

       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.
