L_LTDIC_API L_INT L_DicomSendNCreateResponse(hNet, nPresentationID, nMessageID, pszClass, pszInstance, nStatus, hDS)
| HDICOMNET hNet; | /* a DICOM Network handle */ | 
| L_UCHAR nPresentationID; | /* presentation ID */ | 
| L_UINT16 nMessageID; | /* message ID */ | 
| L_TCHAR * pszClass; | /* class type */ | 
| L_TCHAR * pszInstance; | /* instance */ | 
| L_UINT16 nStatus; | /* status */ | 
| HDICOMDS hDS; | /* data set */ | 
Sends an N-CREATE-RSP message to a peer member of a connection. This function is available in the PACS Imaging 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. | 
| nStatus | The status of the original request. For a list of possible values, refer to Status Constants. | 
| hDS | Data set that contains the information to use when creating the new SOP Instance. | 
Returns
| DICOM_SUCCESS | The function was successful. | 
| >0 | An error occurred. Refer to Return Codes. | 
Comments
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.
