Sends a C-STORE-REQ message to a peer member of a connection. This function is available in the Medical Suite Toolkit.
|
Parameter |
Description |
|
|
hNet |
A DICOM Network handle to the peer member of the connection. |
|
|
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. |
|
|
hDS |
Pointer to the data set to be stored. |
|
Returns
|
0 |
SUCCESS |
|
>0 |
An error occurred. Refer to Return Codes. |
Comments
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 RECEIVECSTOREREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendCStoreResponse which will generate a call to RECEIVECSTORERESPONSECALLBACK.
