The original design (ZLib) does not need to know the uncompressed length. The uncompress function returns an indication that there was not enough memory. This function takes a var parameter which is length of output buffer allocated, on returns the length of the uncompressed data. No big deal, but I...

Madshi, Respectfully disagree. I have two buffers, original data and compressed data. Compressed data goes to a file, preceeded with the length of the compressed data. But I do not always write the the same amount of uncompressed data. So when reading the data back, I know that my buffer of uncompre...

Yes, I found that too a minute ago by stepping through the code.
Doing so, I think there could be a problem in line 3607; my change
(z.TotalInput = dword(srcLen)) and (z.TotalOutput <= dword(dstLen)) then //!!

Output size should be less/equal to capcatity, not equal??

Madshi,

I made that correction but no difference.

Madshi, Trying to use compress / uncompress; the versions with two pointers. When I do compress --> uncompress the uncompressed buffer contains the correct data but the uncompress function returns 0. How do I get the uncompressed length? I expected uncompress to return that value. See code below wha...

Thanks Madshi; problem fixed by downloading the current beta.

I have two Delphi applicactions (32 bits) running on WinXP/64 (or Server 2003 64bit) and I'm trying to use NAmedBuffer.

The function IsWriteAccess always returns false; is there a way around this?
