LDicomNet::OnReceiveCStoreResponse

Summary

Notifies a connection that a C-STORE-RSP command was received. This function is available in the PACS Imaging Toolkit.

Syntax

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

Parameters

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.

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)
   identifies 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
