handle_USR1_signal()

[Bauke Jan Douma]

Hi,

Can someone point out to me how I'm going to use the
handle_USR1_signal() and handle_USR2_signal() hooks in
emacs >21.3?

I would like emacs to dump a list of its currently open
files (buffers) when it receives SIGUSR1.

Vsignal_USR1_hook and Vsignal_USR2_hook were removed
from the current cvs some time ago.
The handler for SIGUSR1 calls kbd_buffer_store_event(&buf),
but I can't figure out where to take it from there from
within emacs.

Thanks for your time.
