Overview

"__builtin_constant_p ( expr )": gcc's compile-time-constant test, typed int. expr is the (unevaluated) operand and token the builtin keyword. The whole expression folds to 1 when expr reduces to a compile-time constant and 0 otherwise — including when it references a variable or a function call, which is not an error here (unlike an ordinary constant expression) but simply yields 0. expr is never evaluated, so it produces no code and no side effects.
