However, the function doc references to return 1/0 needs updates as well. * 1. grab a valid sigcontext into td->live_uc for result analysis: in * such case it returns 1. * * 2. detect if, somehow, a previously grabbed live_uc context has been * used actively with a sigreturn: in such a case the execution would have * magically resumed in the middle of this function itself (seen_already==1): * in such a case return 0, since in fact we have not just simply grabbed * the context. thanks, -- Shuah
