zlibce.dll

[Eduardo Pavinato Klein]

Does anyone has PInvoked zlib.dll?

I think I have a mistake. For example, is it correct to use:

[DllImport("zlibce.dll")]
public static extern IntPtr gzopen (string path, string mode);

for the evc++ function
gzFile gzopen (const char *path, const char *mode);

Thanks,

It looks like the library expects char and not wchar (not 100% sure - just
looked briefly in the headers)
To pass a string as char*, define parameters as byte[]
[DllImport("zlibce.dll")]
public static extern IntPtr gzopen (byte[] path, byte[] mode);

and call it like this:
gzopen (Encoding.ASCII.GetBytes(path), Encoding.ASCII.GetBytes(mode));

you might want to try #ZipLib ?

I had to add the BufferedInputStream code source from mono to make it work
on Pocket.
Otherwise it work straight away, and well. And it's 100% managed.

Thanks Alex.

It's worked like you said.
You are right. The library expects a char *.

Hi Lloyd.

Thanks for the post.
I´ve already used #ZipLib, but ZLIB has a better performance on the Pocket.
