The SunOSTM 5.8 Network Interfaces Programmer's Guide describes the basic facilities to implement distributed applications, and guides the programmer in the use of these facilities.
All utilities, their options, and library functions in this manual reflect SunOS Release 5.8. SunOS 5.8 is a new operating system release developed by Sun Microsystems Inc. If you are using a different version of SunOS, some utilities and library functions might function differently.
A programmer who must convert an existing single-computer application to a networked, distributed application, design a distributed application, implement a distributed application, or maintain a distributed application on the SunOS 5.8 operating system platform should read this manual. Additional techniques for networked applications are described in ONC+ Developer's Guide. This manual assumes basic competence in programming, a working familiarity with the C programming language, and a working familiarity with the UNIX operating system. Previous experience in network programming is helpful, but is not required to use this manual.
The services and capabilities of the Network Interfaces portion of the SunOS 5.8 platform are described in the following pages.
Chapter 1, Introduction to Network Interfaces describes this manual and its intent.
Chapter 2, Socket Interfaces describes the socket interface at the transport layer.
Chapter 3, Programming With XTI and TLI describes the UNIX System V System Transport Level Interface.
Chapter 4, Transport Selection and Name-to-Address Mapping describes the network selection mechanisms used by applications to select a network transport and its configuration.
Appendix A, UNIX Domain Sockets describes UNIX family sockets.
Appendix B, Live Code Example contains complete, functional listings of the code included in the document as examples. These modules are furnished as examples under the provision stated at the beginning of the appendix.
