Comments

Calling LDicomNet::SendAssociateRequest generates a call to LDicomNet::OnReceiveAssociateRequest on the server. Within the callback function the server may accept or reject the Association request by calling LDicomNet::SendAssociateAccept or LDicomNet::SendAssociateReject.

A DICOM Association must be established between an SCU and an SCP before any DICOM messages or data can be transmitted between them. For more information on creating a DICOM Association, refer to Creating a DICOM Associate Connection.

When the DICOM Association is no longer needed, it should be ended. For more information, refer to Closing a DICOM Association.
