Chapter 1 BSD Sockets Concepts

The BSD Sockets facility allows you to create distributed applications that pass data between programs (on the same computer or on separate computers on the network) without requiring an understanding of the many layers of networking protocols. This is accomplished by using a set of system calls. These system calls allow you to create communication endpoints called sockets and transfer data between them.

	NOTE: BSD Sockets is a program development tool. Before you attempt to use BSD Sockets, you may need to familiarize yourself with the C programming language and the HP-UX operating system. You could implement a BSD Sockets application using FORTRAN or Pascal, but all library calls and include files are implemented in C.
