L_INT LDicomNet::SendNReportResponse(nPresentationID, nMessageID, pszClass, pszInstance, nStatus, nEvent, pDS)


L_UCHAR 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.

L_UINT16 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.

L_TCHAR * pszClass

Class affected by the request. This will be an SOP Class or an SOP MetaClass.

L_TCHAR * 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.

L_UINT16 nStatus

The status of the original request. For a list of possible values, refer to Status Constants.

L_UINT16 nEvent

An application specific event for which a report is to be generated.

LDicomDS *pDS

Application specific data set which contains information related to the operation.


Value Meaning
>0 An error occurred. Refer to Return Codes.


LDicomNet::SendNReportResponse is sent by the SCP in response to an LDicomNet::SendNReportRequest call placed by an SCU. This generates a call to LDicomNet::OnReceiveNReportResponse on the SCU.

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.
