P99_UNWIND #define P99_UNWIND (   X )    p00_unwind(p00_unwind_top, p99_unwind_level, (X)) Preliminary resume from one or several levels of nested P99_UNWIND_PROTECT. Parameters X If this evaluates to 0 nothing is done. If it evaluates positive, that number of levels of P99_UNWIND_PROTECT will be unwound. Otherwise all levels on the stack will be unwound and the control variables p99_unwind_code of these will be set to the value of x. Warning Utilities that change control flow in an unexpected way may result in the loss of some modifications that are effected on variables. A modern compiler should tell you when you are in such a situation. If it is the case you'd have to declare the variable in question with the volatile qualifier.
