7*16dce513Schristos  * This header file and associated patches provide a decoder for PKWare's
8*16dce513Schristos  * undocumented deflate64 compression method (method 9).  Use with infback9.c,
9*16dce513Schristos  * inftree9.h, inftree9.c, and inffix9.h.  These patches are not supported.
10*16dce513Schristos  * This should be compiled with zlib, since it uses zutil.h and zutil.o.
11*16dce513Schristos  * This code has not yet been tested on 16-bit architectures.  See the
12*16dce513Schristos  * comments in zlib.h for inflateBack() usage.  These functions are used
13*16dce513Schristos  * identically, except that there is no windowBits parameter, and a 64K
14*16dce513Schristos  * window must be provided.  Also if int's are 16 bits, then a zero for
15*16dce513Schristos  * the third parameter of the "out" function actually means 65536UL.
16*16dce513Schristos  * zlib.h must be included before this header file.
