data set to be moved

Notifies a connection that a C-MOVE-REQ command was received. This function is available in the Medical Imaging Suite 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.
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.
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.
pDS Pointer to the data set to be moved.

Returns

None.

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
