cJSON is a lightweight library for parsing, creating, and modifying JSON data structures within C applications. It provides a comprehensive set of utilities for transforming raw text into navigable objects, manipulating data fields within collections, and serializing complex structures into formatted or unformatted strings.
The library is designed for memory-sensitive and resource-constrained environments, utilizing manual memory management and type-tagged union structures to maintain a minimal footprint. It employs recursive descent parsing and in-place string manipulation to process data efficiently, while representing hierarchies through doubly linked list nodes to facilitate traversal and modification.
The project functions as a self-contained utility with no external dependencies, making it suitable for integration into embedded systems. It provides the necessary tools for managing data interchange and maintaining accurate information states throughout an application lifecycle.
