LDicomNet::OnReceiveNDeleteRequest

#include "ltdic.h"

virtual L_VOID LDicomNet::OnReceiveNDeleteRequest(nPresentationID, nMessageID, pszClass, pszInstance)

L_UCHAR nPresentationID;	/* presentation ID */
L_UINT16 nMessageID;	/* message ID */
L_TCHAR * pszClass;	/* class type */
L_TCHAR * pszInstance;	/* instance */

Notifies a connection that an N-DELETE-REQ command was received. This function is available in the PACS Imaging Toolkit.

Parameter	Description
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 specifies an instance.

Returns

None.

Comments

A call to this function is generated on a peer member of a connection when LDicomNet::SendNDeleteRequest is called locally.

To customize this function, you must derive a class from LDicomNet and override this function.

Example

//In this example:

//1. LMyDicomNet is a class derived from LDicomNet

//2. LMyDicomNet has the following member variables:

// m_nClientOrServer: can be (STATUS_NONE, STATUS_SERVER, STATUS_CLIENT)

// identifieds the LMyDicomNet object as a server or a client

// m_nDataCommand: can be (COMMAND_C_MOVE,COMMAND_C_GET)

// set so the server knows how a C-Store Response was generated

//3. m_pDicomNet points to a valid LMyDicomNet object

// LMyDicomNet *m_pDicomNet

//4. A connection exists between client and server

//5. An association exists between the client and server
