scope_exit(constscope_exit&)=delete; (3)(库基础 TS v3) 从函数、函数对象或另一scope_exit创建scope_exit。 1)以函数或函数对象初始化退出函数。构造的scope_exit为活跃。 若Fn不是左值引用类型且std::is_nothrow_constructible_v<EF, Fn>为true,则以std::forward<Fn>(fn),否则以fn初始化存储的EF。
从创建于另一线程的scope_fail构造scope_fail亦可能导致非预期的行为,因为可能在析构期间比较从另一线程获得的未捕捉异常计数。 示例 运行此代码 #include <iostream>#include <cstdlib>#include <string_view>#include <experimental/scope>voidprint_exit_status(std::string_viewname,boolexit_status,booldid_throw...
