銷燬輸入流。
[編輯] 注意
此解構函式不對底層流緩衝區 (rdbuf()) 執行任何操作：std::basic_ifstream 和 std::basic_istringstream 等派生輸入流的解構函式負責呼叫流緩衝區的解構函式。
[編輯] 示例
執行此程式碼
#include <iostream> #include <sstream> void print_stringbuf(std::streambuf* p) { std::istream buf(p); // buf shares the buffer with s1 int n; buf >> n; std::cout << n; } // calls the destructor of buf. p remains unaffected int main() { std::istringstream s1("10 20"); print_stringbuf(s1.rdbuf()); int n; s1 >> n; std::cout << ',' << n << '\n'; }
