/* infback9.h -- header for using inflateBack9 functions
* Copyright (C) 2003 Mark Adler
* For conditions of distribution and use, see copyright notice in zlib.h
*/
/*
* This header file and associated patches provide a decoder for PKWare's
* undocumented deflate64 compression method (method 9). Use with infback9.c,
* inftree9.h, inftree9.c, and inffix9.h. These patches are not supported.
* This should be compiled with zlib, since it uses zutil.h and zutil.o.
* This code has not yet been tested on 16-bit architectures. See the
* comments in zlib.h for inflateBack() usage. These functions are used
* identically, except that there is no windowBits parameter, and a 64K
* window must be provided. Also if int's are 16 bits, then a zero for
* the third parameter of the "out" function actually means 65536UL.
* zlib.h must be included before this header file.
