stack unwinding

基本解释

I find it convenient to focus on language features rather than on the gruesome details of vtable layout, or stack unwinding (for example).
我覺得我能夠將注意力集中在語言特性本身，而不是vtable佈侷或者棧展開之類的可怕細節，這讓我感覺很好。
Since the compiler generates the code for stack unwinding for every C++ function, this requirement results in a larger executable and slower running code.
因爲編譯器將爲每個 C++ 函數生成進行堆展開的代碼，這種需求將導致更大的可執行文件、更慢的運行代碼。
From a control-flow perspective, an event is a function call, whereas an exception is a long jump across the stack, with unwinding semantics to destroy lost objects.
從控制流的角度看，事件是一次函數調用，而異常則是堆棧的突然跳躍，用展開的語義銷燬丟失的對象。
