Nope, afraid not. Signal handlers would have to use globals.
How is your OO C programming ? A shortcut is that you could:
Declare the descriptor to be static, not auto. Add an extra parameter to
the function that declares the descriptor, which, when set, just returns
it. Them, you can call said function with the parameter that'll cause it
to be returned.
