That's OK except for the last line... the length isn't
necessarily correct so your slice can be wrong.
I'd just use printf or some other function that handles the
zero-terminated char* instead of slicing it.
char[] f = "C:/base/portavox/som/_fon102.wav".dup;
const(wchar)* arq = cast(const(wchar)*)&f;
void* nulo;
uint SND_FILENAME;
PlaySound (arq, nulo, SND_FILENAME);
Oh, that can be much, much, much simpler. Try
PlaySoundW("c:/file.wav"w.ptr, null, SND_FILENAME);
So a few notes:
* SND_FILENAME is a constant defined in the header. You shouldn't
define it yourself, it isn't meant to be a variable.
* The PlaySoundW function takes a wstring, which you can get in D
by sticking the `w` at the end of the literal. So `"foo"` is a
normal string, but `"foo"w` is a wstring. (The difference is
normal is utf-8, wstring is utf-16, which Windows uses
internally.)
* It furthermore takes a pointer, but you want a pointer to data.
A D string or array has a pointer internally you can fetch via
the `.ptr` property. Windows expects this string to be
zero-terminated... which D string literals are, but other D
strings may not be. There's a function in `std.utf` that
guarantees it:
http://dpldocs.info/experimental-docs/std.utf.toUTF16z.html
const(wchar)* safe_to_pass_to_windows = toUTF16z("your string");
