L_INT LDicomNet::SendNDeleteRequest(nPresentationID, nMessageID, pszClass, pszInstance)
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 specifies an instance.
|>0||An error occurred. Refer to Return Codes.|
Calling this function generates a call to LDicomNet::OnReceiveNDeleteRequest on the SCP. The SCP should respond by calling LDicomNet::SendNDeleteResponse which will generate a call to LDicomNet::OnReceiveNDeleteResponse.
This function requests that the SCP delete the specified SOP Instance.
