L_DicomSendNReportRequest

#include "ltdic.h"

L_INT EXT_FUNCTION L_DicomSendNReportRequest(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nEvent, 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 nEvent;	/* event */
HDICOMDS hDS;	/* data set */

Sends an N-REPORT-REQ 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.
nEvent	An application specific event for which a report is to be generated.
hDS	Application specific data set which contains information related to the operation.

Returns

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

Comments

Calling this function generates a call to RECEIVENREPORTREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendNReportResponse which will generate a call to RECEIVENREPORTRESPONSECALLBACK.

A report is generated to let all peers attached to a server know of some event that has occurred. This event may be the addition of a new patient, the deletion of a patient, the addition of a new study, etc. The nEvent value, which designates the event that occurred is determined by the server. To find out the values used, you must contact the organization that created the server. When creating a server, the values and their corresponding meanings are determined by those creating the server.
