Correct me if I'm wrong, but isn't gzuncompress used for 'gzip'
files? Although they both use the same compression, gzip is specific
to files and has header information not present in straight zlib
data. And as I've mentioned, this is a normal file, not compressed --
I'm just trying to read and decompress pieces of data within the file,
which according to the documentation is something zlib does.
I assume that most people use these functions for entire files, but
surely someone has used it the other way as well?
Thanks for any info.

I looked and found a way to turn off buffering for stream *writes*,
but not for stream reads. Can anyone help with ideas for why this
isn't working? I posted questions to comp.lang.php and received no
response.
If all else fails, you could just not use the fancy-pants new stream
and filter functions, and just use http://php.net/zlib directly on
the
file.
Sorry Richard for the double mail, I didn't have the list cc'd
before...
How could I do that? I thought the only way to use zlib in PHP was
through the stream functions.
It's also possible your zlib file is just plain corrupt, and neither
will work...
But I am getting the error before I start to read -- it is not a
zlib 'file', it is a stretch of data within
an ordinary file that has been compressed with zlib.
Thanks
