SDL_version ver;
SDL_GetVersion(&ver);

writeln("version = ", ver); // runs and displays: version = SDL_version(2, 30, 2)

writeln("version = ", SDL_GetVersion(&ver)); // compile fails with

// template writeln is not callable using argument types !()(string, void)
// C:\D\dmd2\windows\bin64....\src\phobos\std\stdio.d(4249,6): Candidate is: writeln(T...)(T args)
// Error C:\D\dmd2\windows\bin64\dmd.exe failed with exit code 1.

I'll confess I can't make heads or tails out of the error messages. Is this impossible or is there some way to make writeln happy?

```c
void SDL_GetVersion(SDL_version * ver);
```

It doesn't return anything.

Its return type is void.

See the argument list where it lists the types of the arguments:

``template writeln is not callable using argument types !()(string, void)``

Which aligns with the arguments you passed to ``writeln``.
