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.
