package.loadlib
Lua function package.loadlib Summary Loads a dynamic link library (DLL) Prototype `f = package.loadlib (libraryname, funcname)` Description `Loads the dynamic library (DLL), and tries to find the entrypoint named "funcname". On success returns the function funcname. On failure returns nil plus 2 error messages. The error might be "The specified module could not be found." if the DLL is not found. You may also get this message if the DLL is dependant on another DLL and that other DLL cannot be found. Use a "dependency checker" to see what DLLs the target DLL might require. If you are certain that the DLL you are requesting exists, then the problem is probably a dependency. The error might be "The specified procedure could not be found." if the function is not found in the DLL. You may also get this message if the DLL is dependant on another DLL and some entry points in that other DLL cannot be found. Use a "dependency checker" to see whether all required entry points have been resolved. If you are certain that the entry point that you are requesting exists in the target DLL, then the problem is probably a dependency from the target DLL to another DLL. You would normally then execute the function (as in the example below) to get it to install the Lua functions into the script space.
    f = assert (package.loadlib ("luacom.dll", "luacom_openlib"))
    f () -- execute function: luacom_openlib
Or, more briefly:
    assert (package.loadlib ("luacom.dll", "luacom_openlib")) ()
