Sends a C-MOVE-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. |
|
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 to which to move the data. |
|
pDS |
Pointer to the data set to be moved. |
Returns
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Comments
Calling this function generates a call to LDicomNet::OnReceiveCMoveRequest on the SCP. The SCP should respond by calling LDicomNet::SendCMoveResponse which will generate a call to LDicomNet::OnReceiveCMoveResponse.
