When to Use STREAMS

The STREAMS framework is most useful when modularity and configurability are issues. For instance, network drivers, terminal drivers, and graphics I/O device drivers benefit from using STREAMS. Modules can be pushed (added) and popped (removed) to create desired program behavior.

STREAMS is general enough to provide modularity between a range of protocols. It is a major component in networking support utilities for UNIX System V because it facilitates communication between network protocols.
