`dylib.dlsym` is used to get the function address.
`dylib.dlcall` is used to call the function, the first argument is the function address, make sure this argument is vm_obj and type=obj_extern.
`dylib.dlcall` is used to call the function, the first argument is the function address, make sure this argument is `vm_obj` and `type=obj_extern`.
`dylib.dlclose` is used to unload the library, at the moment that you call the function, all the function addresses that got from it are invalid.
`dylib.limitcall` is used to get `dlcall` function that has limited parameter size, this function will prove the performance of your code because it does not use `vm_vec` to store the arguments, instead it uses local scope to store them, so this could avoid frequently garbage collecting. And the code above could also be written like this:
```javascript
var dlhandle=dylib.dlopen("libfib."~(os.platform()=="windows"?"dll":"so"));
var fib=dylib.dlsym(dlhandle,"fib");
var invoke=dylib.limitcall(1); # this means the called function has only one parameter
for(var i=1;i<30;i+=1)
println(invoke(fib,i));
dylib.dlclose(dlhandle);
```
If get this, Congratulations!
```bash
