That's how they are in soundmgr.hxx (they're two different functions - one
is passing in an FGSimpleSound pointer to the sound manager and the other
the file name.)
I've found the proper answer to my problem now - I was doing:
FGSimpleSound simple("temp01.wav");
globals->get_soundmgr()->add(&simple, refname);
which doesn't work, whereas the following does work:
FGSimpleSound* simple = new FGSimpleSound("temp01.wav");
globals->get_soundmgr()->add(simple, refname);
In my initial case, when simple went out of scope when my function
returned, this must have been leaving the sound manager with no
FGSimpleSound, and causing the fatal error. Thus no compile time error,
but it wouldn't work.
I guess I need to chant "A POINTER IS NOT THE SAME AS A REFERENCE" or
possibly "THE STACK IS NOT THE SAME AS THE HEAP" a couple of thousand
times!
Given that I also got bitten by the
char* str = "Hello";
is not the same as
char str[] = "Hello";
business a few days ago, I feel like I've been slapped repeatedly around
the head with a giant cod with C/C++ written on it!!
Cheers - Dave
