6. Where's the zlib documentation (man pages, etc.)? |
It's in zlib.h . Examples of zlib usage are in the files test/example.c |
and test/minigzip.c, with more in examples/ . |

13. How can I make a Unix shared library? |
By default a shared (and a static) library is built for Unix. So: |
make distclean |
./configure |
make clean |
./configure -s |
make |

correctly points to the zlib specification in RFC 1950 for the "deflate" |
transfer encoding, there have been reports of servers and browsers that |
incorrectly produce or expect raw deflate data per the deflate |
specification in RFC 1951, most notably Microsoft. So even though the |
specficiation in RFC 1951, most notably Microsoft. So even though the |
"deflate" transfer encoding using the zlib format would be the more |
efficient approach (and in fact exactly what the zlib format was designed |
for), using the "gzip" transfer encoding is probably more reliable due to |

ZLIB DATA COMPRESSION LIBRARY |
zlib 1.2.8 is a general purpose data compression library. All the code is |
zlib 1.2.5 is a general purpose data compression library. All the code is |
thread safe. The data format used by the zlib library is described by RFCs |
(Request for Comments) 1950 to 1952 in the files |
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and |
rfc1952 (gzip format). |
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) |
and rfc1952.txt (gzip format). |
All functions of the compression library are documented in the file zlib.h |
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example |
of the library is given in the file test/example.c which also tests that |
the library is working correctly. Another example is given in the file |
test/minigzip.c. The compression library itself is composed of all source |
files in the root directory. |
of the library is given in the file example.c which also tests that the library |
is working correctly. Another example is given in the file minigzip.c. The |
compression library itself is composed of all source files except example.c and |
minigzip.c. |
To compile all files and run the test program, follow the instructions given at |
the top of Makefile.in. In short "./configure; make test", and if that goes |
well, "make install" should work for most flavors of Unix. For Windows, use |
one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use |
well, "make install" should work for most flavors of Unix. For Windows, use one |
of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use |
make_vms.com. |

single call of inflate), the parameter flush should be set to Z_FINISH. In |
this case all pending input is processed and all pending output is flushed; |
avail_out must be large enough to hold all of the uncompressed data for the |

required to perform an inflation in one step. However it may be used to |
inform inflate that a faster approach can be used for the single inflate() |
call. Z_FINISH also informs inflate to not maintain a sliding window if the |
stream completes, which reduces inflate's memory footprint. If the stream |

used to inform inflate that a faster approach may be used for the single |
inflate() call. |
In this implementation, inflate() always flushes as much output as |
possible to the output buffer, and always uses the faster approach on the |
first call. So the effects of the flush parameter in this implementation are |

If a preset dictionary is needed after this call (see inflateSetDictionary |
below), inflate sets strm->adler to the Adler-32 checksum of the dictionary |

"a" can be used instead of "w" to request that the gzip stream that will |
be written be appended to the file. "+" will result in an error, since |
reading and writing to the same gzip file is not supported. The addition of |
"x" when writing will create the file exclusively, which fails if the file |
already exists. On systems that support it, the addition of "e" when |
reading or writing will set the flag to close the file on an execve() call. |
These functions, as well as gzip, will read and decode a sequence of gzip |
streams in a file. The append function of gzopen() can be used to create |
such a file. (Also see gzflush() for another way to do this.) When |
appending, gzopen does not test whether the file begins with a gzip stream, |
nor does it look for the end of the gzip streams to begin appending. gzopen |
will simply append a gzip stream to the existing file. |
gzopen can be used to read a file which is not in gzip format; in this |
case gzread will directly read from the file without decompression. When |
reading, this will be detected automatically by looking for the magic two- |
byte gzip header. |

fd. If you want to keep fd open, use fd = dup(fd_keep); gz = gzdopen(fd, |
mode);. The duplicated descriptor should be saved to avoid a leak, since |
gzdopen does not close fd if it fails. If you are using fileno() to get the |
file descriptor from a FILE *, then you will have to use dup() to avoid |
double-close()ing the file descriptor. Both gzclose() and fclose() will |
close the associated file descriptor, so they need to have different file |
descriptors. |
gzdopen does not close fd if it fails. |
gzdopen returns NULL if there was insufficient memory to allocate the |

Upon reaching the end of the input, gzread will return with the available |

gzclearerr can be used to clear the end of file indicator in order to permit |
gzread to be tried again. Z_OK indicates that a gzip stream was completed |
on the last gzread. Z_BUF_ERROR indicates that the input file ended in the |
middle of a gzip stream. Note that gzread does not return -1 in the event |
of an incomplete gzip stream. This error is deferred until gzclose(), which |
will return Z_BUF_ERROR if the last gzread ended in the middle of a gzip |
stream. Alternatively, gzerror can be used before gzclose to detect this |
