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.  

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.
