How do I have a function return with a "Return from Interrupt"
instead of a "Return from Subroutine"?

I have ended up doing:

volatile void intr_handler(void)
{

	/* Do stuff */

	asm("RTI"); /* RTI is my assembler's return from interrupt */
}

(Of course, I am still getting: warning: `volatile' function does return).

Is there something like an "interrupt" attribute or
a pragma or something for a function to do this?

Thanks in advance,

++ Carlos
