#include "ltdic.h"

L_INT EXT_FUNCTION L_DicomSendNActionResponse(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nStatus, nAction, hDS)

HDICOMNET hNet;	/* a DICOM Network handle */
L_UCHAR nPresentationID;	/* presentation ID */
L_UINT16 nMessageID;	/* message ID */
L_CHAR * pszClass;	/* class type */
L_CHAR * pszInstance;	/* instance */
L_UINT16 nStatus;	/* status */
L_UINT16 nAction;	/* the action performed */
HDICOMDS hDS;	/* data set */

Sends an N-ACTION-RSP message to a peer member of a connection. This function is available in the Medical Suite Toolkit.

Parameter	Description
hNet	A DICOM Network handle to the peer member of the connection.
nPresentationID	Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.
nMessageID	Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
pszClass	Class affected by the request. This will be an SOP Class or an SOP MetaClass.
pszInstance	The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.
nStatus	The status of the original request. For a list of possible values, refer to Status Constants.
nAction	An application specific action that was performed on the specified data set.
hDS	Data set resulting from the specified action.

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.
