COM-API

The COM-API is a Windows-like interface that enables you to write new programs for the server-based Message Stream Interface (MSI) more easily. This interface makes it possible to read HPOM messages from the internal message stream, and to write messages into the internal message stream. The MSI is available on HPOM managed nodes. All MSI types establish a connection to the HPOM message agent.
