## Overview

lib_string is a small C library that wraps a NUL-terminated buffer with size and capacity in a String type. Its principal workflow is to create a String, inspect or print it, then release it; the sample program demonstrates this with both an empty value and a C-string value. The library also provides length queries, comparisons, and deep or truncated duplication. The graph focuses on runtime behavior; the README describes the sample as a place to try the library. The available excerpts do not show calls for every API module.
