Defined in header <cstdlib>
[[noreturn]] void quick_exit( int exit_code ) noexcept;		(since C++11)

Causes normal program termination to occur without completely cleaning the resources.

Functions passed to std::at_quick_exit are called in reverse order of their registration. If an exception tries to propagate out of any of the functions, std::terminate is called. After calling the registered functions, calls std::_Exit(exit_code)

Functions passed to std::atexit are not called.

Parameters

exit_code

-

exit status of the program

Return value

(none)
