[Rd] Check for interrupts

[Gabor Csardi]

Dear All,

is there a portable way to test from C whether there are interrupts (ie.
ctrl+c) to handle. I know there is R_CheckUserInterrupt() but i would need
to call some functions before handling the interrupt. On unix something like

if (R_interrupts_pending) {
   my_cleanup_function();
   R_CheckUserInterrupt();
}

might work, but this definitely does not work on windows (and possibly also
not on osx). 

Or i need to install finalizers? Could you recommend some up to date docs
and/or examples if this is the case?

Thank you,
Gabor
