problem with class_is_ui()

Hi.

I can’t get class_is_ui() working. If I build my source with a call to class_is_ui(), I have a “Symbol(s) not found” linker error.

I’m on Xcode 3.2.2, SDK 5.1.1.

Does anyone have a clue?

Some investigation shows that this function is exported on Windows but not on the Mac. I will fix this for Max 5.1.5.

best,
Tim

Thank you… I can live without it for the moment, and I’ll wait for 5.1.5.

FWIW, it’s just a simple function that tests the CLASS_FLAG_UIOBJECT class flag.

long class_is_ui(t_class *c)
{
long val = 0;

if (c && (c->c_flags & CLASS_FLAG_UIOBJECT)) {
val = 1;
}
return val;
}

Thank you Joshua.
in fact, this is more or less what I had done instead.
cheers
