L_LTDIC_API L_INT L_DicomSendCMoveRequest(hNet, nPresentationID, nMessageID, pszClass, nPriority, pszMoveAE, hDS)
Sends a C-MOVE-REQ message to a peer member of a connection.
A DICOM Network handle to the peer member of the connection.
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.
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.
Class affected by the request. This will be an SOP Class or an SOP MetaClass.
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. |
Character string that contains the name of the application entity to which to move the data.
Pointer to the data set to be moved.
Value | Meaning |
---|---|
DICOM_SUCCESS | The function was successful. |
>0 | An error occurred. Refer to Return Codes. |
Calling this function generates a call to RECEIVECMOVEREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendCMoveResponse which will generate a call to RECEIVECMOVERESPONSECALLBACK.
