Notifies a connection that a C-STORE-REQ command was received. This function is available in the Medical 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. |
|
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. |
|
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_PRIORTY_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. |
|
nMoveMessageID |
The ID of the original move request message. For a simple storage request from a client to a server, this should be 0. When the request is a sub-operation of a C-MOVE, this will contain the original message ID of the C-MOVE request. |
|
pDS |
Pointer to the data set to be stored. |
Returns
None.
Comments
A call to this function is generated on a peer member of a connection when LDicomNet::SendCStoreRequest is called.
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
