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 failed due to resource limitations.

DAT_INVALID_HANDLE

The ia_handle parameter is invalid.

DAT_INVALID_PARAMETER
