本文主要是介绍ZLIB 1.2.8 压缩整理，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
ZLIB 官网：http://www.zlib.net/ ，有详细的英文文档及代码。
ZLIB 数据压缩相关结构体：
typedef struct z_stream_s {z_const Bytef *next_in; /* next input byte */uInt avail_in; /* number of bytes available at next_in */uLong total_in; /* total number of input bytes read so far */Bytef *next_out; /* next output byte should be put there */uInt avail_out; /* remaining free space at next_out */uLong total_out; /* total number of bytes output so far */z_const char *msg; /* last error message, NULL if no error */struct internal_state FAR *state; /* not visible by applications */alloc_func zalloc; /* used to allocate the internal state */free_func zfree; /* used to free the internal state */voidpf opaque; /* private data object passed to zalloc and zfree */int data_type; /* best guess about the data type: binary or text */uLong adler; /* adler32 value of the uncompressed data */uLong reserved; /* reserved for future use */
} z_stream;相关枚举值：
