-1) I need a Windows DLL
-2) I need a Visual Basic interface to zlib
-3) compress() returns Z_BUF_ERROR
-4) deflate or inflate returns Z_BUF_ERROR
-5) Where is the zlib documentation (man pages, etc...)?
-6) Why don't you use GNU autoconf, libtool, etc...?
-7) There is a bug in zlib.
-8) I get "undefined reference to gzputc"
+ 1. Is zlib Y2K-compliant?
 
+    Yes. zlib doesn't handle dates.
 
+ 2. Where can I get a Windows DLL version?
 
-1) I need a Windows DLL
+    The zlib sources can be compiled without change to produce a DLL. If you
+    want a precompiled DLL, see http://www.winimage.com/zLibDll/ . Questions
+    about the zlib DLL should be sent to Gilles Vollant (info@winimage.com).

+ 4. compress() returns Z_BUF_ERROR
 
-  See http://www.tcfb.com/dowseware/cmp-z-it.zip

-  and contrib/visual-basic.txt
+    Make sure that before the call of compress, the length of the compressed
+    buffer is equal to the total size of the compressed buffer and not
+    zero. For Visual Basic, check that this parameter is passed by reference
+    ("as any"), not by value ("as long").
 
-3) compress() returns Z_BUF_ERROR
+ 5. deflate() or inflate() returns Z_BUF_ERROR
 
-  Make sure that before the call of compress, the length of the
-  compressed buffer is equal to the total size of the compressed buffer
-  and not zero.  For Visual Basic, check that this parameter is passed
-  by reference ("as any"), not by value ("as long").
+    Before making the call, make sure that avail_in and avail_out are not
+    zero. When setting the parameter flush equal to Z_FINISH, also make sure
+    that avail_out is big enough to allow processing all pending input.
 
+ 6. Where's the zlib documentation (man pages, etc.)?
 
-4) deflate or inflate returns Z_BUF_ERROR
+    It's in zlib.h for the moment, and Francis S. Lin has converted it to a
+    web page zlib.html. Volunteers to transform this to Unix-style man pages,
+    please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage
+    are in the files example.c and minigzip.c.
 
-  Make sure that before the call avail_in and avail_out are not zero.
+ 7. Why don't you use GNU autoconf or libtool or ...?
 
+    Because we would like to keep zlib as a very small and simple
+    package. zlib is rather portable and doesn't need much configuration.
 
-5) Where is the zlib documentation (man pages, etc...)?
+ 8. I found a bug in zlib.
 
-  It's in zlib.h for the moment. Volunteers to transform this
-  to man pages, please contact jloup@gzip.org. Examples of zlib usage
-  are in the files example.c and minigzip.c.
+    Most of the time, such problems are due to an incorrect usage of
+    zlib. Please try to reproduce the problem with a small program and send
+    the corresponding source to us at zlib@gzip.org . Do not send
+    multi-megabyte data files without prior agreement.
 
+ 9. Why do I get "undefined reference to gzputc"?
 
-6) Why don't you use GNU autoconf, libtool, etc...?
+    If "make test" produces something like
 
-  Because we would like to keep zlib as a very small and simple package.

+       example.o(.text+0x154): undefined reference to `gzputc'
+      
+    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+    /usr/X11R6/lib. Remove any old versions, then do "make install".
 
+10. I need a Delphi interface to zlib.
 
-7) There is a bug in zlib.
+    See the directories contrib/delphi and contrib/delphi2 in the zlib
+    distribution.
 
-  Most of the time, such problems are due to an incorrect usage
-  of zlib. Please try to reproduce the problem with a small
-  program and send us the corresponding source at zlib@quest.jpl.nasa.gov
-  Do not send multi-megabyte data files without prior agreement.
+11. Can zlib handle .zip archives?
 
+    See the directory contrib/minizip in the zlib distribution.
 
-8) I get "undefined reference to gzputc"
+12. Can zlib handle .Z files?
 
-  If "make test" produces something like
-     example.o(.text+0x174): 
-  check that you don't have old files libz.* in /usr/lib, /usr/local/lib
-  or /usr/X11R6/lib. Remove old versions then do "make install".
+    No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
+    the code of uncompress on your own.
 
+13. How can I make a Unix shared library?
+
+    make clean
+    ./configure -s
+    make
+
+14. Why does "make test" fail on Mac OS X?
+
+    Mac OS X already includes zlib as a shared library, and so -lz links the
+    shared library instead of the one that the "make" compiled. For zlib
+    1.1.3, the two are incompatible due to different compile-time
+    options. Simply change the -lz in the Makefile to libz.a, and it will use
+    the compiled library instead of the shared one and the "make test" will
+    succeed.
+
+15. I have a question about OttoPDF
+
+    We are not the authors of OttoPDF. The real author is on the OttoPDF web
+    site Joel Hainley jhainley@myndkryme.com.

-The changes made in version 1.1.3 are documented in the file ChangeLog.
-The main changes since 1.1.2 are:
-
-- fix "an inflate input buffer bug that shows up on rare but persistent
-  occasions" (Mark)
-- fix gzread and gztell for concatenated .gz files (Didier Le Botlan)
-- fix gzseek(..., SEEK_SET) in write mode
-- fix crc check after a gzeek (Frank Faubert)
-- fix miniunzip when the last entry in a zip file is itself a zip file
-  (J Lillge)
-- add contrib/asm586 and contrib/asm686 (Brian Raiter)
-  See http://www.muppetlabs.com/~breadbox/software/assembly.html
-- add support for Delphi 3 in contrib/delphi (Bob Dellaca)
-- add support for C++Builder 3 and Delphi 3 in contrib/delphi2 (Davide Moretti)
-- do not exit prematurely in untgz if 0 at start of block (Magnus Holmgren)
-- use macro EXTERN instead of extern to support DLL for BeOS (Sander Stoks)
-- added a FAQ file

+The changes made in version 1.1.4 are documented in the file ChangeLog.
+The only changes made since 1.1.3 are bug corrections:
+
+- ZFREE was repeated on same allocation on some error conditions.
+  This creates a security problem described in
+  http://www.zlib.org/advisory-2002-03-11.txt
+- Returned incorrect error (Z_MEM_ERROR) on some invalid data
+- Avoid accesses before window for invalid distances with inflate window
+  less than 32K.
+- force windowBits > 8 to avoid a bug in the encoder for a window size
+  of 256 bytes. (A complete fix will be available in 1.1.5).
+
+The beta version 1.1.5beta includes many more changes. A new official
+version 1.1.5 will be released as soon as extensive testing has been
+completed on it.

+<a name="Introduction"><h2> Introduction </h2>
+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+  <p>
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+  <p>
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio.
+  <p>
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.
+  <p>
+
+<hr>
+<a name="Utility functions"><h2> Utility functions </h2>
+     The following utility functions are implemented on top of the
+   <a href="#Basic functions">basic stream-oriented functions</a>. 
+   To simplify the interface, some
+   default options are assumed (compression level and memory usage,
+   standard memory allocation functions). The source code of these
+   utility functions can easily be modified if you need special options.

+   <p>
+     <a href="#gzflush">gzflush</a> should be called only when strictly necessary because it can

+
+<font color="Blue"><dt> z_off_t     <a name="gzseek">gzseek</a> (gzFile file, z_off_t offset, int whence);</font>
+<dd>
+      Sets the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
+   given compressed file. The offset represents a number of bytes in the
+   uncompressed data stream. The whence parameter is defined as in lseek(2);
+   the value SEEK_END is not supported.
+   <p>
+     If the file is opened for reading, this function is emulated but can be
+   extremely slow. If the file is opened for writing, only forward seeks are

+   would be before the current position.
+   <p>
+
+<font color="Blue"><dt> int     <a name="gzrewind">gzrewind</a> (gzFile file);</font>
+<dd>
+     Rewinds the given file. This function is supported only for reading.

+<dd>
+     Returns the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
+   given compressed file. This position represents a number of bytes in the
+   uncompressed data stream.
+   <p>
+
+   <a href="#gztell">gztell</a>(file) is equivalent to <a href="#gzseek">gzseek</a>(file, 0L, SEEK_CUR)

+
+<font color="Blue"><dt> int  <a name="gzeof">gzeof</a> (gzFile file);</font>
+<dd>
+     Returns 1 when EOF has previously been detected reading the given
+   input stream, otherwise zero.
+   <p>
+
+<font color="Blue"><dt> int     <a name="gzclose">gzclose</a> (gzFile file);</font>
+<dd>
+     Flushes all pending output if necessary, closes the compressed file
+   and deallocates all the (de)compression <a href="#state">state</a>. The return value is the zlib
+   error number (see function <a href="#gzerror">gzerror</a> below).
+   <p>
+
+<font color="Blue"><dt> const char *  <a name="gzerror">gzerror</a> (gzFile file, int *errnum);</font>
+<dd>
+     Returns the error message for the last error which occurred on the
+   given compressed file. errnum is set to zlib error number. If an
+   error occurred in the file system and not in the compression library,
+   errnum is set to <a href="#Z_ERRNO">Z_ERRNO</a> and the application may consult errno
+   to get the exact error code.

+   <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and <a href="#opaque">opaque</a> must be initialized before by the caller.
+   If <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> are set to <a href="#Z_NULL">Z_NULL</a>, <a href="#deflateInit">deflateInit</a> updates them to

+
+<font color="Blue"><dt>  int  <a name="deflate">deflate</a> (<a href="#z_streamp">z_streamp</a> strm, int flush);</font>
+<dd>
+    <a href="#deflate">deflate</a> compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.<p>
+
+    The detailed semantics are as follows. <a href="#deflate">deflate</a> performs one or both of the
+  following actions:
+
+  <ul>
+  <li> Compress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> are updated and
+    processing will resume at this point for the next call of <a href="#deflate">deflate</a>().
+
+  <li> 
+    Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a>
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+  </ul> <p>
+
+  Before the call of <a href="#deflate">deflate</a>(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating <a href="#avail_in">avail_in</a> or <a href="#avail_out">avail_out</a> accordingly ; <a href="#avail_out">avail_out</a>
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (<a href="#avail_out">avail_out</a> == 0), or after each call of <a href="#deflate">deflate</a>(). If <a href="#deflate">deflate</a> returns <a href="#Z_OK">Z_OK</a>
+  and with zero <a href="#avail_out">avail_out</a>, it must be called again after making room in the
+  output buffer because there might be more output pending.
+  <p>
+
+    If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  <a href="#avail_in">avail_in</a> is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+  <p>
+
+    If flush is set to <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a>, all output is flushed as with
+  <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, and the compression <a href="#state">state</a> is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a> too often can seriously degrade
+  the compression.
+  <p>
+
+    If <a href="#deflate">deflate</a> returns with <a href="#avail_out">avail_out</a> == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  <a href="#avail_out">avail_out</a>), until the flush is complete (<a href="#deflate">deflate</a> returns with non-zero
+  <a href="#avail_out">avail_out</a>).
+  <p>
+
+    If the parameter flush is set to <a href="#Z_FINISH">Z_FINISH</a>, pending input is processed,
+  pending output is flushed and <a href="#deflate">deflate</a> returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> if there
+  was enough output space ; if <a href="#deflate">deflate</a> returns with <a href="#Z_OK">Z_OK</a>, this function must be
+  called again with <a href="#Z_FINISH">Z_FINISH</a> and more output space (updated <a href="#avail_out">avail_out</a>) but no
+  more input data, until it returns with <a href="#Z_STREAM_END">Z_STREAM_END</a> or an error. After
+  <a href="#deflate">deflate</a> has returned <a href="#Z_STREAM_END">Z_STREAM_END</a>, the only possible operations on the
+  stream are <a href="#deflateReset">deflateReset</a> or <a href="#deflateEnd">deflateEnd</a>.
+  <p>
+  
+    <a href="#Z_FINISH">Z_FINISH</a> can be used immediately after <a href="#deflateInit">deflateInit</a> if all the compression
+  is to be done in a single step. In this case, <a href="#avail_out">avail_out</a> must be at least
+  0.1% larger than <a href="#avail_in">avail_in</a> plus 12 bytes.  If <a href="#deflate">deflate</a> does not return
+  <a href="#Z_STREAM_END">Z_STREAM_END</a>, then it must be called again as described above.
+  <p>
+
+    <a href="#deflate">deflate</a>() sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all input read
+  so far (that is, <a href="#total_in">total_in</a> bytes).

+    <a href="#inflate">inflate</a> decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may some
+  introduce some output latency (reading input without producing any output)
+  except when forced to flush.
+  <p>
+
+  The detailed semantics are as follows. <a href="#inflate">inflate</a> performs one or both of the
+  following actions:
+
+  <ul>
+  <li> Decompress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), <a href="#next_in">next_in</a> is updated and processing
+    will resume at this point for the next call of <a href="#inflate">inflate</a>().
+
+  <li> Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and 
+    <a href="#avail_out">avail_out</a> accordingly.  <a href="#inflate">inflate</a>() provides as much output as possible, 
+    until there is no more input data or no more space in the output buffer 
+    (see below about the flush parameter).
+  </ul> <p>
+
+  Before the call of <a href="#inflate">inflate</a>(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (<a href="#avail_out">avail_out</a> == 0), or after each
+  call of <a href="#inflate">inflate</a>(). If <a href="#inflate">inflate</a> returns <a href="#Z_OK">Z_OK</a> and with zero <a href="#avail_out">avail_out</a>, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+  <p>
+
+    If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, <a href="#inflate">inflate</a> flushes as much
+  output as possible to the output buffer. The flushing behavior of <a href="#inflate">inflate</a> is
+  not specified for values of the flush parameter other than <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>
+  and <a href="#Z_FINISH">Z_FINISH</a>, but the current implementation actually flushes as much output
+  as possible anyway.
+  <p>
+
+    <a href="#inflate">inflate</a>() should normally be called until it returns <a href="#Z_STREAM_END">Z_STREAM_END</a> or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of <a href="#inflate">inflate</a>), the parameter flush should be set to
+  <a href="#Z_FINISH">Z_FINISH</a>. In this case all pending input is processed and all pending
+  output is flushed ; <a href="#avail_out">avail_out</a> must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be <a href="#inflateEnd">inflateEnd</a> to deallocate the decompression <a href="#state">state</a>. The use of <a href="#Z_FINISH">Z_FINISH</a>
+  is never required, but can be used to inform <a href="#inflate">inflate</a> that a faster routine
+  may be used for the single <a href="#inflate">inflate</a>() call.
+  <p>
+
+     If a preset dictionary is needed at this point (see <a href="#inflateSetDictionary">inflateSetDictionary</a>
+  below), <a href="#inflate">inflate</a> sets strm-<a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of the
+  dictionary chosen by the compressor and returns <a href="#Z_NEED_DICT">Z_NEED_DICT</a> ; otherwise 
+  it sets strm-&gt <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all output produced
+  so far (that is, <a href="#total_out">total_out</a> bytes) and returns <a href="#Z_OK">Z_OK</a>, <a href="#Z_STREAM_END">Z_STREAM_END</a> or
+  an error code as described below. At the end of the stream, <a href="#inflate">inflate</a>()
+  checks that its computed <a href="#adler32">adler32</a> checksum is equal to that saved by the
+  compressor and returns <a href="#Z_STREAM_END">Z_STREAM_END</a> only if the checksum is correct.
+  <p>
+
+    <a href="#inflate">inflate</a>() returns <a href="#Z_OK">Z_OK</a> if some progress has been made (more input processed
+  or more output produced), <a href="#Z_STREAM_END">Z_STREAM_END</a> if the end of the compressed data has
+  been reached and all uncompressed output has been produced, <a href="#Z_NEED_DICT">Z_NEED_DICT</a> if a
+  preset dictionary is needed at this point, <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect
+  <a href="#adler32">adler32</a> checksum), <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the stream structure was inconsistent
+  (for example if <a href="#next_in">next_in</a> or <a href="#next_out">next_out</a> was NULL), <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not
+  enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if no progress is possible or if there was not

+   the caller.<p>
+
+     The method parameter is the compression method. It must be <a href="#Z_DEFLATED">Z_DEFLATED</a> in
+   this version of the library.<p>
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   <a href="#deflateInit">deflateInit</a> is used instead.<p>
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression <a href="#state">state</a>. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio ; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.<p>
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value <a href="#Z_DEFAULT_STRATEGY">Z_DEFAULT_STRATEGY</a> for normal data, <a href="#Z_FILTERED">Z_FILTERED</a> for data produced by a
+   filter (or predictor), or <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a> to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to <a href="#compress">compress</a> them better. The effect of <a href="#Z_FILTERED">Z_FILTERED</a> is to force more
+   Huffman coding and less string matching ; it is somewhat intermediate
+   between Z_DEFAULT and <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a>. The strategy parameter only affects

+
+     The dictionary should consist of strings (byte sequences) that are likely
+   to be encountered later in the data to be compressed, with the most commonly
+   used strings preferably put towards the end of the dictionary. Using a
+   dictionary is most useful when the data to be compressed is short and can be
+   predicted with good accuracy ; the data can then be compressed better than
+   with the default empty dictionary.<p>
+
+     Depending on the size of the compression data structures selected by
+   <a href="#deflateInit">deflateInit</a> or <a href="#deflateInit2">deflateInit2</a>, a part of the dictionary may in effect be
+   discarded, for example if the dictionary is larger than the window size in
+   <a href="#deflate">deflate</a> or deflate2. Thus the strings most likely to be useful should be
+   put at the end of the dictionary, not at the front.<p>
+

+   The application must update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> when <a href="#avail_in">avail_in</a> has
+   dropped to zero. It must update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a> when <a href="#avail_out">avail_out</a>
+   has dropped to zero. The application must initialize <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and
+   <a href="#opaque">opaque</a> before calling the init function. All other fields are set by the
+   compression library and must not be updated by the application. <p>
+
+   The <a href="#opaque">opaque</a> value provided by the application will be passed as the first
+   parameter for calls of <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a>. This can be useful for custom
+   memory management. The compression library attaches no meaning to the
+   <a href="#opaque">opaque</a> value. <p>
+
+   <a href="#zalloc">zalloc</a> must return <a href="#Z_NULL">Z_NULL</a> if there is not enough memory for the object.
+   If zlib is used in a multi-threaded application, <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> must be
+   thread safe. <p>
+
+   On 16-bit systems, the functions <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this
+   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
+   pointers returned by <a href="#zalloc">zalloc</a> for objects of exactly 65536 bytes *must*
+   have their offset normalized to zero. The default allocation function
+   provided by this library ensures this (see zutil.c). To reduce memory
+   requirements and avoid any allocation of 64K objects, at the expense of
+   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
+   <p>
+
+   The fields <a href="#total_in">total_in</a> and <a href="#total_out">total_out</a> can be used for statistics or
+   progress reports. After compression, <a href="#total_in">total_in</a> holds the total size of
+   the uncompressed data and may be saved for use in the decompressor
+   (particularly if the decompressor wants to decompress everything in
+   a single step). <p>
