NAME

dat_cno_create - create a CNO instance

SYNOPSIS

cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>

DAT_RETURN
dat_cno_create (
IN DAT_IA_HANDLE ia_handle,
IN DAT_OS_WAIT_PROXY_AGENT agent,
OUT DAT_CNO_HANDLE *cno_handle
)

PARAMETERS

ia_handle
Handle for an instance of DAT IA.


agent
An optional OS Wait Proxy Agent that is to be invoked
whenever CNO is invoked. DAT_OS_WAIT_PROXY_AGENT_NULL
indicates that there is no proxy agent


cno_handle
Handle for the created instance of CNO.

DESCRIPTION

The dat_cno_create() function creates a CNO instance. Upon creation,
there are no Event Dispatchers feeding it.


The agent 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
DAT_OS_WAIT_PROXY_AGENT_NULL specifies that no OS Wait Proxy Agent is
associated with the created CNO.


Upon creation, the CNO is not associated with any EVDs, has no
waiters and has, at most, one OS Wait Proxy Agent.

RETURN VALUES

DAT_SUCCESS
The operation was successful.


DAT_INSUFFICIENT_RESOURCES
The operation failed due to resource
limitations.


DAT_INVALID_HANDLE
The ia_handle parameter is invalid.


DAT_INVALID_PARAMETER
One of the parameters was invalid, out
of range, or a combination of
parameters was invalid, or the agent
parameter is invalid.
