RE: Will Lua work in this situation?

["Alexander Altshuler" <alt@...>]

You must declare your function 
__declspec(dllexport) int my_c_function(lua_State* L)
{
...
}

or use  .def file in project.

I am trying this method, but it is not working, I am making mistake  
someware :( I am working on Windows, staretd a dll project (Visual
Studio  
2005), and written as given below

int my_c_function(lua_State* L)
{
   const char* name = luaL_checkstring(L, 1);
   printf("Hello %s!\n", name);
   return 0;
}

only "dll" file is generated (no lib file), then when I try to call

local my_c_function = assert(package.loadlib("mylib.dll",
"my_c_function"))

 from my Lua interpreter I get this error

stdin:1: The specified procedure could not be found.

stack traceback:
         [C]: in function 'assert'
         stdin:1: in main chunk
         [C]: ?

I again tried with changing the "my_c_function" like this

int __declspec(dllexport) my_c_function(lua_State* L)
{
   const char* name = luaL_checkstring(L, 1);
   printf("Hello %s!\n", name);
   return 0;
}

Again I am getting the same error message. Where am I making mistake?

Thanks for your help,
  Lloyd
