7 Socket Interfaces

This chapter describes the socket interface. Sample programs are included to illustrate key points. The following topics are discussed in this chapter:

• Socket creation, connection, and closure are discussed in Socket Basics.

• Client-Server architecture is discussed in Client-Server Programs.

• Advanced topics such as multicast and asynchronous sockets are discussed in Advanced Socket Topics.

• Interfaces used to implement the Stream Control Transmission Protocol (SCTP) are discussed in Stream Control Transmission Protocol.

Note:

The interface that is described in this chapter is multithread safe. You can call applications that contain socket interface calls freely in a multithreaded application. The degree of concurrency that is available to applications is not specified.
