Sends a Release Request message to a connection. This function is available in the PACS Imaging Toolkit.

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

Calling LDicomNet::SendReleaseRequest generates a call to LDicomNet::OnReceiveReleaseRequest on the server. The server will call LDicomNet::SendReleaseResponse which will generate a call to LDicomNet::OnReceiveReleaseResponse on the client. At this time the DICOM Association may be closed. For more information, refer to Ending a DICOM Association.

Please note that this method of closing a DICOM Association is preferable to just calling LDicomNet::SendAbort.

{
//In this example, the m_pDicomNet object sends a release request to the peer.
//The m_pDicomNet object can point to an object that is a server or a client
//
//LMyDicomNet is a class derived from LDicomNet
//m_pDicomNet is a member variable declared as:
//    LMyDicomNet *m_pDicomNet;
//m_nStatus is member variable that identifies whether LDicomNet object is a server or client
//m_nStatus can be (STATUS_NONE, STATUS_SERVER, STATUS_CLIENT)
//    int m_nStatus;
//
//
//In this example, assume
//1. m_pDicomNet points to a valid object
//2. A connection exists between client and server
//3. An associate request has been sent and accepted
//4. m_nStatus is either STATUS_SERVER or STATUS_CLIENT
