Note unless you wrote the code or you reverse engineer it.

If you have Visual Studio or Visual C++, then you can use its utility called dumpbin, which will give you all the functions names.

then, you must run the program that uses the dll, and use the VC++' Spy++ tool to trace a function call and see what parameters are passed to it when it is called

Also with Visual Studio is a program called depends.exe that will show the functions

Use the DLL DbgHelp.dll (see MSDN for the complete list of contained functions) to access a Dll, find the exported functions and unmangle the names (UnDecorateSymbolName().)

This paper gives a rough view of how others have used the interface http://www.drizzle.com/~scottb/gdc/fubi-paper.htm (starting at the section "Name mangling is a C++ feature ....")

Hope that's a start!

Hello,

You can find the functions for managing PE exes and dlls in ImageHlp.dll. Borland provides a .pas wrapper for this with Delphi.

You can find a sample application and code on how to use the ImageRvaToVa to access the export table here http://www.swissdelphicenter.ch/en/showcode.php?id=1133

Hope that was useful.
