LDicomNet::OnReceiveCMoveRequest

Summary

Notifies a connection that a C-MOVE-REQ command was received. This function is available in the Medical Imaging Suite Toolkit.

Syntax

#include "ltdic.h"

virtual L_VOID LDicomNet::OnReceiveCMoveRequest(nPresentationID, nMessageID, pszClass, nPriority, pszMoveAE, pDS)

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_UINT16 nPriority

The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect. Possible values are:

Value	Meaning
COMMAND_PRIORITY_LOW	[0x0002] Low priority message.
COMMAND_PRIORITY_MEDIUM	[0x0000] Medium priority message.
COMMAND_PRIORITY_HIGH	[0x0001] High priority message.

L_TCHAR * pszMoveAE

Character string that contains the name of the application entity that originally requested the move. For a simple storage request from a client to a server, this should be ". When the request is a sub-operation of a C-MOVE, this will contain the name of the AE that requested the move.

LDicomDS* pDS

Pointer to the data set to be moved.

Returns

None.

Comments

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

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

Example

In this example:

LMyDicomNet is a class derived from LDicomNet
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
m_pDicomNet points to a valid LMyDicomNet object
LMyDicomNet *m_pDicomNet
A connection exists between client and server

An association exists between the client and server
