How to get list of functions inside a DLL (managed and unmanaged)?

Question

So I play around a DLL (UnityEditor.dll) I wanna to get a list of all functions inside of this managed DLL which are unmanaged (dll is probably composed from a native C++ (with statically compiled libaries if such were used) core and managed C++ wrapper all wrapped into one dll.) I want to get a list of all unmanaged functions inside of that Dll to for example create my own managed\unmanaged wrapper?

say functions that were defined as `extern C ...` or something like that — myWallJSON, Jul 25 '12 at 20:45
The UnityEditor.dll is a managed dll, and all it does is wrap calls to Unity's C++ code. You can view its code using dotPeek. — Ilya Suzdalnitski, Oct 16 '14 at 06:08

The dumpbin.exe utility shipped with Visual Studio can be used to display a list of exports. For example:

dumpbin.exe /EXPORTS C:\WINDOWS\System32\Kernel32.dll

Example output:

Microsoft (R) COFF/PE Dumper Version 10.00.30319.01

Dump of file C:\Windows\System32\kernel32.dll

File Type: DLL

  Section contains the following exports for KERNEL32.dll

    00000000 characteristics

        0.00 version

        1390 number of functions

          6    5 0006ADF0 AddConsoleAliasA
          7    6 0006AE60 AddConsoleAliasW

all I get from it is: C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC>dumpbin.exe /EXPORTS "C:\Program Files (x86)\ppp \UnityEngine.dll" Microsoft (R) COFF/PE Dumper Version 10.00.40219.01 Copyright (C) Microsoft Corporation.

@myWallJSON, then there are no functions exported by that DLL. You could investigate the other options to `dumpbin`. — hmjd, Jul 25 '12 at 21:52
even "ALL" does not provide any info. the unmanaged DLL is wrapped inside a native one=( — myWallJSON, Jul 26 '12 at 10:58

Open the .dll file and look for the EXPORT section of this PE file using the binary PE/COFF specs available from Microsoft.

But that's an overkill, I think. Your question should be a concrete want. What exactly do you want to wrap and what do you have ? Only the binaries and no source/headers ?

DLLs don't contain "functions". They contain code and entrypoints. It's not possible to tell from optimized code where transitions between functions occur unless you have a debug database.
