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
