WANDIO is a library for reading from, and writing to, files. Depending on libraries available at compile time, WANDIO provides transparent compression/decompression for the following formats: - zlib (gzip) - bzip2 - lzo (write-only) - lzma - zstd - lz4 - Intel QAT (write-only) - http (read-only) WANDIO also improves IO performance by performing compression/decompression in a separate thread (if pthreads are available).
