Tools for debugging STREAMS-based applications are discussed in this section. They fall into one of three categories:

• STREAMS debug printing provides facilities for printing messages on the console from inside STREAMS drivers and modules.

• STREAMS error logging is a model for generating error messages and having them received by one of two different types of loggers.

• STREAMS examination tools are bundled with the WindNet STREAMS component.
