data set to be stored |
Sends a C-STORE-REQ message to a peer member of a connection. 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. | |
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. | |
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. |
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
When an SCU requests a Move (C-MOVE-REQ), the SCP may have to call this function 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.
Calling this function generates a call to LDicomNet::OnReceiveCStoreRequest on the SCP. The SCP should respond by calling LDicomNet::SendCStoreResponse which will generate a call to LDicomNet::OnReceiveCStoreResponse.
