If you ATSFontActivateFromFileSpecification() from a file on a CD,
you'll need to ATSFontDeactivate() if you expect to ever remove the CD.

myfonts is born empty. No need to empty it again.

It is good, that you assign the return value to osstatus. But, you
should check, as you do above, that osstatus == noErr.

You'll need to free ioArray before returning

Remove the [f release] : since you don't init or copy f, you shouldn't
release it.
Here, you need an: f=nil;
Think about what would happen if, the third time through the loop,
fontName was nil.

Remove the [f release] : since you don't init or copy f, you shouldn't
release it.

Remove the CFRelease(path) : since you don't init or copy path, you
shouldn't release it.
