示例1: prep

bool error = false;
// prep prototype and check for errors
ExprPrototypeNode* prototype = (ExprPrototypeNode*)child(0);

functionEnv.resetAndSetParent(&env);
if (!prototype->prep(false, functionEnv).isValid()) error = true;
// decide what return type we want
bool returnWantsScalar = false;
if (!error && prototype->isReturnTypeSet()) returnWantsScalar = prototype->returnType().isFP(1);
// prep block and check for errors
