virtual L_VOID LDicomNet::OnReceiveCStoreResponse(nPresentationID, nMessageID, pszClass, pszInstance, nStatus)

/* message ID */

L_TCHAR * pszClass;

/* class type */

L_TCHAR * pszInstance;

L_UINT16 nStatus;

/* status */

Notifies a connection that a C-STORE-RSP 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 identifies the data with a specific instance.

nStatus

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

Returns

None.

Comments

A call to this function is generated on an SCU when LDicomNet::SendCStoreResponse is called by an SCP.

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

When an SCU requests a Move (C-MOVE-REQ), the SCP may have to call LDicomNet::SendCStoreRequest to request one or more C-STORE-REQ sub-operations to complete the storage. The series of calls and information transfer in a C-MOVE-REQ is complicated. For more information, refer to Moving Composite Data.

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
