L_LTDIC_API L_INT L_DicomSendNCreateResponse(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nStatus, hDS)
Sends an N-CREATE-RSP message to a peer member of a connection. This function is available in the PACS Imaging Toolkit.
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 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.
The status of the original request. For a list of possible values, refer to Status Constants.
Data set that contains the information to use when creating the new SOP Instance.
Value | Meaning |
---|---|
DICOM_SUCCESS | The function was successful. |
>0 | An error occurred. Refer to Return Codes. |
L_DicomSendNCreateResponse is sent by the SCP in response to an L_DicomSendNCreateRequest call placed by an SCU. This generates a call to RECEIVENCREATERESPONSECALLBACK on the SCU.
