Sends an N-DELETE-REQ message to a peer member of a connection. 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. |
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Calling this function generates a call to LDicomNet::OnReceiveNDeleteRequest on the SCP. The SCP should respond by calling LDicomNet::SendNDeleteResponse which will generate a call to LDicomNet::OnReceiveNDeleteResponse.
This function requests that the SCP delete the specified SOP Instance.

{
//This example sends an N-Delete Request to a server
//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
