This chapter discusses the concept of ports in Open Transport and introduces the Open Transport functions that provide information about the ports available on your computer.

You need to read this chapter if your application has the ability to use multiple ports, and you need to be able to obtain port information.

This chapter discusses how your application can

• browse available ports and get specific port information

• register as an Open Transport client

• handle yield port requests

This chapter begins by introducing basic concepts about ports, then gives the details of how to find a specific port and extract information about it, and explains how to register your application as an Open Transport client. For complete information about the data types and functions used to work with ports, see "Ports Reference".
