The UUID generator uuidgen is an interactive utility that creates UUIDs (universal unique identifiers). A UUID is a hexadecimal number that contains information that makes it unique from all other UUIDs. Applications use UUIDs to identify many kinds of entities, including interface definitions. Consequently, application developers typically use the UUID generator when they are creating their interface definition files.
To run the UUID generator, issue the uuidgen command. This command offers several options, including an option to create a template interface definition file (an .idl file) containing a newly generated interface UUID. For complete information about generating UUIDs and template interface definition files, see the OSF DCE Application Development Guide - Core Components. See this volume also for a discussion of UUIDs and their use in DCE applications. Refer to the uuidgen(1rpc) reference page for a description of the uuidgen utility and its options.
