I am trying to decompress an http receive buffer that is content-encoded using
gzip and am having some problems. Here is the info I have so far; you take a
look and let me know where i might be going wrong?
1) I am assuming I should be using zlib
2) I statically linked the palmos patched 1.1.4 zlib library and added zlib.h
and zconf.h to my PODS program (i'm not using syszlib.h because it appears that
syszlib.h is only good for the shared library setup because it requires a
refnum,etc.)
3) I setup a function similar to the zlib example on the zlib homepage that
uses inflate.
4) inflateinit works well, but when i call inflate i get an error on the 2nd
byte with a message "unknown compression method"
5) Is this because the inflate function uses the zlib inflate algorithm, as
opposed to the gzip algorithm?
6) I would try using the gz functions, but they only work with files and I have
a memory buffer. The latest version of zlib says you can call inflateinit2 and
use the gzip algorithm with a buffer instead of the zlib algorithm, but I
haven't been able to compile/link the latest version without compile/link
errors.
7) My questions are:
A) How do I use the zlib 1.1.4 library to decompress a http memory buffer
with gzip content-encoding?
B) Does anything above look incorrect?
C) I read through RFC 1952 (gzip spec) and my memory buffer appears to
have the correct header (at least the first few hex values are correct) so I'm
assuming that isn't the problem.
Thanks for any help you can provide,
Troy
