[Mono-dev] Understanding ZipSharp and Native(Un)Zip - any MonoPosixHelper gurus?
I'm hoping someone familiar with MonoPosixHelper and/or WindowsBase will see this. I am attempting to port System.IO.Package to iOS. I have made some progress, to the point where my somewhat stripped-down WindowsBase is compiling under Xamarin on the Mac, and I can run the Packaging functions to the point of decompressing the file. Following through the code, this appears to ultimately fail on this: [DllImport (MonoPosixHelper, CallingConvention=CallingConvention.Cdecl)] static extern int unzOpenCurrentFile2 (UnzipHandle handle, out int method, out int level, int raw); Looking over MonoPosixHelper, it *appears* this consists largely of Zlib. Zlib is already installed on Mac/iOS in /usr/lib. So, in theory, P/Invoke should work given a few tweaks to the DllImport. However, I cannot find any function called unzOpenCurrentFile2 in MonoPosixHelper. I found some sort of mapping in WindowBase's IOFunctions.cs, but I'm not sure I understand it's purpose, nor if it is in any way related to this. I can't shake the feeling that simply changing that DllImport is all I need, but I am too confused by the naming to be sure. Any pointers would be greatly appreciated! p.s. My apologies if this double-posts, I got some sort of bounce message. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

I'm not really familiar with MonoPosixHelper, but it looks like on mobile it uses the __Internal P/Invoke: https://github.com/mono/mono/blob/f39bebefeaa15cdde051d428f6bdc7e3e80b2c10/mcs/class/System/System.IO.Compression/DeflateStream.cs#L480-L484 Maybe that helps. -- Alex From: maury.markow...@gmail.com Date: Thu, 30 Oct 2014 10:05:50 -0400 To: mono-devel-list@lists.ximian.com Subject: [Mono-dev] Understanding ZipSharp and Native(Un)Zip - any MonoPosixHelper gurus?

It may indeed. I only had the Win version so I did not see this code, so I'll go get the MONOTOUCH code and compare. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
