如何从Debug文件中得到函数的参数类型和个数

[verybigbug]

如何用编程的方法从Debug文件中得到函数的参数类型和个数？
我看WinDbg就可以得到函数的定义，就可以得到参数的个数，用的
是哪个函数？SymGetXxxx?
有没有Sample?

Platform SDK: Debugging and Error Handling
Symbol Paths
The library uses the symbol search path to locate debug symbols (.dbg file) for .dll, .exe, and .sys files by appending "\symbols" and "\dll" or "\exe" or "\sys" to the path. For example, the typical location of symbol files for .dll files is c:\mysymbols\symbols\dll. For .exe files, the location is c:\mysymbols\symbols\exe.

To specify where the symbol handler will search disk directories for symbol files, call the SymSetSearchPath function. Alternatively, you can specify a symbol search path in the UserSearchPath parameter of the SymInitialize function.

The UserSearchPath parameter in SymInitialize and the SearchPath parameter in SymSetSearchPath take a pointer to a null-terminated string that specifies a path, or series of paths separated by a semicolon. The symbol handler uses these paths to search for symbol files. If this parameter is specified as a non-null value, the symbol handler searches only the paths set by the application. If this parameter is NULL, the symbol handler first searches the current working directory of the application, then the system root directory (%windir%). If you set the _NT_SYMBOL_PATH or _NT_ALT_SYMBOL_PATH environment variable, the symbol handler searches for symbol files in the following order:

The current working directory of the application.
The _NT_SYMBOL_PATH environment variable.
The _NT_ALT_SYMBOL_PATH environment variable.
To retrieve the search paths, call the SymGetSearchPath function.

The search path for program database (.pdb) files is different than the path for debug (.dbg) files. The algorithm is determined by the functionality of the symbol library. By default, Microsoft Visual C/C++ creates Microsoft format symbols, strips them from the image, and places them in a separate .pdb file. Typically, the .pdb file will be located in the directory that contains the executable image. Visual C/C++ embeds the absolute path to the .pdb file in the executable image. If the symbol handler cannot find the .pdb file in that location or if the .pdb file was moved to another directory, the symbol handler will locate the .pdb file using the search path described for .dbg files.

我看过，只能得到函数名，得不到参数和本地变量等详细的信息。
不知道用哪个函数。SymGetSymFormAddr只能得到函数名！！！

看了一下MSDN，好像PDB格式是不公开的，VC5.0和VC6.0就有点不一样！
靠，真的没办法吗？有没有MS的人将内部MSPDB60.DLL的函数接口资料公开
一下？----估计MS中国也没这么核心的资料吧！

只好放弃。。。。
