例如,如果您原本參考 std::future_status::future_status 類型,則現在必須改為 std::future_status。 不過,大部分的程式碼不會受影響,例如 std::future_status::ready 仍會編譯。 explicit operator bool() 會比運算子 unspecified-bool-type() 更為嚴格。 explicit operator bool() 允許明確轉換為 bool (例如...
For example, if you referred to the type std::future_status::future_status, now you have to say std::future_status. However, most code is unaffected—for example, std::future_status::ready still compiles. explicit operator bool() is stricter than operator unspecified-bool-type(). explicit...

导致程序按正常方式立即终止。status作为送给执行环境的出口值,0表示成功结束,两个可用的常数为EXIT_SUCCESS,EXIT_FAILURE。 3)正常终止注册函数atexit。 原型是: 可用本函数把一些函数注册为结束动作。被注册函数应当是无参无返回值的函数。注册正常完成时atexit返回值0,否则返回非零值。 6.与执行环境交互 1)向执行...

pid_t waitpid(pid_t pid, int*status, int options) 作用和 wait() 完全相同,但是多了两个可由用户控制的参数 pid 和 options。 pid 参数指示一个子进程的 ID,表示只关心这个子进程退出的 SIGCHLD 信号。如果 pid=-1 时,那么和 wait() 作用相同,都是关心所有子进程退出的 SIGCHLD 信号。
