L_LTDIC_API L_INT L_DicomSendNCreateRequest(hNet, nPresentationID, nMessageID, pszClass, pszInstance, hDS)
Sends an N-CREATE-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 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.
Data set with the information to use when creating.
Value | Meaning |
---|---|
DICOM_SUCCESS | The function was successful. |
>0 | An error occurred. Refer to Return Codes. |
Calling this function generates a call to RECEIVENCREATEREQUESTCALLBACK on the SCP. The SCP should respond by calling L_DicomSendNCreateResponse which will generate a call to RECEIVENCREATERESPONSECALLBACK.
This function creates a new SOP Instance on the specified peer connection. The data set with the new information must be created and filled before calling this function.
Required DLLs and Libraries
Win32, x64, Linux.
