The Guide to Writing DCE Applications is a hands-on programming guide to OSF's Distributed Computing Environment (DCE) for first-time DCE application programmers. This book is designed to help new DCE users make the transition from conventional nondistributed applications programming to distributed DCE programming. Topics include the IDL and ACF files, essential RPC calls, binding methods and the name service, server initialization, memory management, object UUIDs, authentication and authorization (basic security), and other selected advanced topics. Several small, practical programming examples are included. The second edition of this book extends the step-by-step treatment to two advanced topics: object UUIDs and security. Object UUIDs let the client select resources on the server side. Security enforces access on the basis of who the client or server is. This book does not discuss Access Control Lists, a more advanced area of security. We believe the programmer writing her first DCE application will find this book the perfect resource. The Guide to Writing DCE Applications is designed to get the programmer up and running with working examples of client/server applications and to provide a comprehensive model for the development of distributed applications. Contents include:

• Overview of a distributed application
• Using a DCE RPC interface (IDL and ACF files)
• Developing clients
• Using pointers and arrays
• Developing a server
• Using a name service
• Resource selection through object UUIDs
• Security (authentication/authorization) for both client and server
• Using a context handle to maintain server state
• Using pipes for large quantities of data
Quick references
• Complete code for seven applications, plus Makefiles and directions for building and running
