dat_cno_query(3DAT) Direct Access Transport Library Functions dat_cno_query(3DAT)NAME
dat_cno_query - provide the Consumer parameters of the CNO
SYNOPSIS
cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>
DAT_RETURN
dat_cno_query (
IN DAT_CNO_HANDLE cno_handle,
IN DAT_CNO_PARAM_MASK cno_param_mask,
OUT DAT_CNO_PARAM *cno_param
)
PARAMETERS
cno_handle Handle for the created instance of the Consumer Notification Object
cno_param_mask Mask for CNO parameters
cno_param Pointer to a Consumer-allocated structure that the Provider fills with CNO parameters
DESCRIPTION
The dat_cno_query() function provides the Consumer parameters of the CNO. The Consumer passes in a pointer to the Consumer-allocated struc-
tures for CNO parameters that the Provider fills.
The cno_param_mask parameter allows Consumers to specify which parameters to query. The Provider returns values for cno_param_mask
requested parameters. The Provider can return values for any other parameters.
A value of DAT_OS_WAIT_PROXY_AGENT_NULL in cno_param indicates that there are no Proxy Agent associated with the CNO.
RETURN VALUES
DAT_SUCCESS The operation was successful.
DAT_INVALID_PARAMETER The cno_param_mask parameter is invalid.
DAT_INVALID_HANDLE The cno_handle parameter is invalid.

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.
