9 * This header file and associated patches provide a decoder for PKWare's
10 * undocumented deflate64 compression method (method 9).  Use with infback9.c,
11 * inftree9.h, inftree9.c, and inffix9.h.  These patches are not supported.
12 * This should be compiled with zlib, since it uses zutil.h and zutil.o.
13 * This code has not yet been tested on 16-bit architectures.  See the
14 * comments in zlib.h for inflateBack() usage.  These functions are used
15 * identically, except that there is no windowBits parameter, and a 64K
16 * window must be provided.  Also if int's are 16 bits, then a zero for
17 * the third parameter of the "out" function actually means 65536UL.
18 * zlib.h must be included before this header file.
