I cant eject cd wen my application once read from cd.Pleas..

Hai all
I newbie in cocoa.I am now with font manager devolopment. The proj
want to read font from CD.I can read data from cd and use the data.but
I cant to eject cd wen application loaded and readed once from CD.After
reading i read font from system font. then also i cant eject cd .CD
can eject only after closing application .
Wen try to close then a dialog box appears with "one application is
using cd close application and try".
I tried by removing all datas from arrays used,but then also cant
eject.

The pgm. work with font is below .please check that i hav missed any
code to be added with this to remove control over directory that is
currently using.

I have no idea about FSRef,FSpath,ATSFontRef.If anyone of the above
want to release or deallocate.I think one of them are continuing
control of cd wen once read data from cd.Wat i will do to eject cd wen
app. is running.Ejecting cd is for changing the cd and try it with
another cd.

Excuse my english .Please help

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.
