Having hard time to make it work on C# to be honest.. :(

Code:
[DllImport("quickbms.dll", EntryPoint = "quickbms_compression")]
        private static extern int quickbms_compression(string algo, byte[] inData, int zsize, byte[] outData, int size);

        private void testCompression()
        {
            var rr = quickbms_compression("", null, 1000, null, 5000);

        }



Not sure if this is correct, dont know how to properly declarate it and how to write decompress and compress functions... :(

Hi Aluigi, we have finally found some time and implemented small wrapper around your great quickbms dll tool for C# and it works great for decompression and encryption / decryption. The only problem we now have is with compression and hashes - zlib_compress or deflate_compress etc. does not work like they should ( - error in src\extra\xalloc.c line 678: xdbg_realloc()
Error: memory allocation problem), we have also tested NULL array as output data, which eliminates error, but produces no comprimed data (returned size is zero). As for hashes, we have no idea how to get the computed hash - so far it returns identical data as input. If currently not possible / implemented with hashes -
we suggest another separate interface for hashes with custom hash output (instead of replacing input) and hash_size (in byte form is fine) is an option or replace input completely by resizing input array to default hash size (after computation - but this option is least favored)

ok for compression I understand what's the problem, it's exactly what it says so a problem during allocation because the compression "reallocates" the buffers which is something impossible with the buffers provided externally from your tool.
The quickbms_hash variable can't be read from the dll.
Added to my TODO list and will check what I can do in the next release, consider that (re)compression and hashing are not exactly the features I was thinking to for the dll, I made it mainly for the decompression and encryption that you confirmed work correctly.

Nice thx for info and btw great job. Main reason to do this is to use compression and decompression and encryption in own tools, so compress is very important in this case as well.

Code:
putarray 0 0 -0.534796
putarray 1 0 -2.33745618
putarray 2 0 -1.77319
putarray 3 1 0.199748
putarray 4 1 1.900874
putarray 5 1 2.44347639
...
let's just assume i'm going to write a bms script that needs this many "arrays"(about 70 ARRAY-s per 20 VAR_IDX-es each, or 1 ARRAY per 80 VAR_IDX-es each if you will) to even do anything - surely i'm not going to write it like this
point is, i need a simplified putarray command so that having to come up with gigantic arrays stored within a bunch of indexes doesn't turn out to be an exercise in patience and frustration

Do you mean something like the following?

putarray 0 -1 VALUE
putarray 0 -1 VALUE
putarray 0 -1 VALUE
...
putarray 1 -1 VALUE
putarray 1 -1 VALUE
...
sortarray 0 1 # the last 1 will automatically applying the sorting to all the arrays and not just to array 0

kinda like that yaa

although what i had in mind was more like this
Code:
putarray 0-2 0 -0.534796 -2.33745618 -1.77319
putarray 3-5 1 0.199748 1.900874 2.44347639

if something is completely different than the expected syntax (PutArray ARRAY VAR_IDX VAR) then it can't be simple at all.

The only space available is after the 3rd argument which is reserved for future usages, anyway quickbms supports a limited number of arguments (a bit less than 32).

I kiss your hands Luigi Auriemma for all of your efforts !
Providing of quickbms as dll must be a new generation !
I ashamed to say you even in my current age i am not properly familiar with programming of codes that insert dll commands !!!
I begging for a very very simple tutorial may be in c++ that show how to use quickbms DLL ?
