You can read a resource fork easily through the standard C library given
a file name by appending "/rsrc" to it, so for:
/Users/foobar/Library/Fonts/FrabNuts
fopen("/Users/foobar/Library/Fonts/FrabNuts/rsrc","rb")
The format of a resource fork isn't hard to parse, there is code in
fontforge (in the file macbinary.c of the ff source distribution) to do
this (I may even have added it to freetype at one point).
I'm not volunteering for this at the moment, because I've got my own
work to do, but I can talk someone through it if that would be helpful

This I don't know how to do.
