HAVEZLIB

HAVEZLIB is a header file and associated library functions used in C and C++ programming for handling data compression and decompression using the zlib compression library. The zlib library is a widely adopted, royalty-free, general-purpose data compression library, and HAVEZLIB provides the necessary declarations and definitions to integrate zlib's functionality into a C or C++ project.

The primary purpose of HAVEZLIB is to expose the core zlib API, allowing developers to compress and decompress data streams. This is commonly used for tasks such as reducing file sizes, optimizing network data transfer, and storing data efficiently. The library supports the DEFLATE compression algorithm, which is a lossless compression method.

Key functions provided through HAVEZLIB include those for initializing compression and decompression streams, processing data chunks, and finalizing the stream operations. It allows for both in-memory compression and decompression as well as file-based operations. The library handles the complexities of the DEFLATE algorithm, including managing compression levels and window sizes, abstracting these details away from the developer. HAVEZLIB is often included in projects that need to work with compressed data formats that utilize zlib, such as PNG images, ZIP archives, and various network protocols. Its availability and widespread use make it a fundamental tool for developers dealing with data size optimization.
