RDMA_CREATE_EVENT_CHANNEL(3)				   Librdmacm Programmer's Manual			      RDMA_CREATE_EVENT_CHANNEL(3)

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 rea- son.
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.
