Common Lisp Cookbook - Streams
Summary
The Common Lisp Cookbook's Streams chapter explains the stream abstraction in Lisp, detailing input, output, and bidirectional streams, their element types, and how to test capabilities. It covers standard stream variables, file and string streams, concatenated and broadcast streams, two-way and echo streams, Gray streams, and practical examples for reading, writing, and redirecting output. It also provides references to the CLHS, CLtL, and related libraries.
