rdma_create_event_channel
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.
