Newbie: can't manage some types...

[Cleverson Casarin Uliana via Digitalmars-d-learn]

Thank you very much, Adam, now I'm receiving another strange error. My
code is this:

import core.sys.windows.mmsystem;

void main() {
PlaySoundW("C:/base/portavox/som/_fon102.wav"w.ptr, null, SND_FILENAME);
}

When trying to compile, it returns:
OPTLINK (R) for Win32  Release 8.00.17

tocaSom.obj(tocaSom)
 Error 42: Symbol Undefined _PlaySoundW at 12
--- errorlevel 1

I made some quick searches, but not sure whether there is some error
messages' index ?

Thanks for helping,
Cleverson
