std::at_quick_exit(3) C++ Standard Libary std::at_quick_exit(3) NAME std::at_quick_exit - std::at_quick_exit Synopsis Defined in header <cstdlib> int at_quick_exit( /*atexit-handler*/* func ) noexcept; (1) (since C++11) int at_quick_exit( /*c-atexit-handler*/* func ) noexcept; extern "C++" using /*atexit-handler*/ = void(); // exposition-only (2) extern "C" using /*c-atexit-handler*/ = void(); // exposition-only Registers the function pointed to by func to be called on quick pro- gram termination (via std::quick_exit). Calling the function from several threads does not induce a data race. The implementation shall support the registration of at least 32 func- tions. The registered functions will not be called on normal program termi- nation. If a function need to be called in that case, std::atexit must be used. Parameters func - pointer to a function to be called on quick program termina- tion Return value 0 if the registration succeeds, nonzero value otherwise. Notes The two overloads are distinct because the types of the parameter func are distinct (language linkage is part of its type) Example This section is incomplete Reason: no example See also abort causes abnormal program termination (without cleaning up) (function) exit causes normal program termination with cleaning up (function) atexit registers a function to be called on std::exit() invoca- tion (function) quick_exit causes quick program termination without completely cleaning up (C++11) (function) http://cppreference.com 2022.07.31 std::at_quick_exit(3)
