Sending and Receiving Messages

Once an ISCL connection has been established, the client and the server are ready to start transferring messages and data. The data transferred may be secured or unsecured. To send unsecured messages, the user should use the L_DicomSendNonSecureISCL function.

Use the L_DicomSetMaxMessageLengthISCL function to set the maximum message length that can be processed.

For information about confidentiality and data integrity associated with sending secured messages, refer to Adding Security to a DICOM Connection.

Since encryption modes, message authentication codes, authorization data and message length must all match between a sender and a receiver, occasionally, a sender will send a message that is not received properly by the receiver. When this happens, the receiver, not the sender, can get information about the problems that caused the failure. LEADTOOLS provides the following functions to help the user locate the cause of the problem:

L_DicomGetPeerAuthDataISCL

L_DicomGetPeerEncryptionISCL

L_DicomGetPeerMACISCL

L_DicomGetPeerRequestedMessageLengthISCL

In addition, when errors occur, the L_DicomGetErrorSecure and L_DicomGetStatusISCL can be used to help determine the location of the problem.
