Name
       RDMA_WRITE_CM_EVENT - Write an event into a CM.

SYNOPSIS
       #include <rdma/rdma_cma.h>

       int rdma_write_cm_event(struct rdma_cm_id *id, enum rdma_cm_event_type
       event, int status, uint64_t arg);

ARGUMENTS
       id      The RDMA identifier associated with the reported rdma_cm_event.

       event   The communication event value to report. This should be set to
       RDMA_CM_EVENT_USER.

       status  The status value reported in the rdma_cm_event.

       arg     A user-specified value reported in the rdma_cm_event.

DESCRIPTION
       Write an event into a CM, with a status and an argument.

RETURN VALUE
       On success 0 is returned, on error -1 is returned, errno will be set to
       indicate the failure reason.

NOTES
       This call allows an application to write a user-defined event to the
       event channel associated with the specified rdma_cm_id. Valid user
       events are: RDMA_CM_EVENT_USER. Applications may use this for internal
       signaling purposes, such as waking a thread blocked on the event
       channel.
