[Openal-devel] Using C++ in ALUT?

[Killian De Volder]

IMO,
Depends on who "owns" the code .
But you could wrap it (and don't compile it, but offer it as a header 
(so you don't get overhead)) :
Ow and we'd need a new standard to allow this (otherwise it will not 
work on all  openal implementations) very important !!!

namespace OpenAl{
    class Stream{
       public:
           Stream(std::string file){
               alutStream *stream = 
alutCreateStreamFromFile("somefile.ogg");
           }
           bool IsPlaying(){ return alutStreamIsPlaying(stream)}
       private:
            alutStream *stream;
    }
}
...

You get the idea :)
Performance overhead ? 1 function call worst case.
Is it standard ??? HELL NO !!! (We'd need a new standard from it, (can't 
stress it enough :D ) ).

(That's my 2 cents)
