std::sig_atomic_t(3) C++ Standard Libary std::sig_atomic_t(3) NAME std::sig_atomic_t - std::sig_atomic_t Synopsis Defined in header <csignal> typedef /* unspecified */ sig_atomic_t; An integer type which can be accessed as an atomic entity even in the presence of asynchronous interrupts made by signals. Notes Until C++11, which introduced std::atomic and std::atomic_signal_fence, about the only thing a strictly conforming program could do in a signal handler was to assign a value to a volatile static std::sig_atomic_t variable and promptly re- turn. See also signal sets a signal handler for particular signal (function) atomic_signal_fence fence between a thread and a signal handler executed in the same (C++11) thread (function) C documentation for sig_atomic_t http://cppreference.com 2024.06.10 std::sig_atomic_t(3)
