2 STREAMS Mechanism and System Calls

This chapter describes system calls that create, use, and close a stream. The stream head processes the

system calls that are made by a user level process. These system calls provide the user level facilities needed

to develop applications.

This chapter describes the following:

• Creating a stream or a streams based pipe

• Writing to a stream

• Reading from a stream

• Pushing a module into a stream

• Popping a module from a stream:

• Closing a stream

• Polling a stream

• Asynchronous event notification

• Attaching and detaching a stream to a file
