DAT_RETURN
    dat_cno_create (
    IN    DAT_IA_HANDLE            ia_handle,

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.
