.SH DESCRIPTION
.sp
.LP
The \fBdat_cno_create()\fR function creates a CNO instance. Upon creation, there are no Event Dispatchers feeding it.
.sp
.LP
The \fIagent\fR parameter specifies the proxy agent, which is OS-dependent and which is invoked when the CNO is triggered. After it is invoked, it is no longer associated with the CNO. The value of \fBDAT_OS_WAIT_PROXY_AGENT_NULL\fR specifies that no OS Wait Proxy Agent is associated with the created CNO.
.sp
.LP
Upon creation, the CNO is not associated with any EVDs, has no waiters and has, at most, one OS Wait Proxy Agent.
