Gzip format files (created with the gzip program, for example) use the "deflate" compression algorithm, which is the same compression algorithm as what zlib uses. However, when using zlib to inflate a gzip compressed file, the library returns a Z_DATA_ERROR.

How can I use zlib to decompress a gzip file?
