是否有任何本机 DLL 导出函数查看器？

you can use Dependency Walker to view the function name. you can see the function's parameters only if it's decorated. read the following from the FAQ:

How do I view the parameter and return types of a function? For most functions, this information is simply not present in the module. The Windows' module file format only provides a single text string to identify each function. There is no structured way to list the number of parameters, the parameter types, or the return type. However, some languages do something called function "decoration" or "mangling", which is the process of encoding information into the text string. For example, a function like int Foo(int, int) encoded with simple decoration might be exported as _Foo@8. The 8 refers to the number of bytes used by the parameters. If C++ decoration is used, the function would be exported as ?Foo@@YGHHH@Z, which can be directly decoded back to the function's original prototype: int Foo(int, int). Dependency Walker supports C++ undecoration by using the Undecorate C++ Functions Command.

If you don't have the source code and API documentation, the machine code is all there is, you need to disassemble the dll library using something like IDA Pro , another option is use the trial version of PE Explorer.

PE Explorer provides a Disassembler. There is only one way to figure out the parameters: run the disassembler and read the disassembly output. Unfortunately, this task of reverse engineering the interface cannot be automated.

PE Explorer comes bundled with descriptions for 39 various libraries, including the core Windows® operating system libraries (eg. KERNEL32, GDI32, USER32, SHELL32, WSOCK32), key graphics libraries (DDRAW, OPENGL32) and more.

DLL Export Viewer by NirSoft can be used to display exported functions in a DLL.

This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.
