{
// The intent is to propose the following for addition to namespace std
// in the C++ Standard Library, and to then deprecate EXIT_SUCCESS and
// EXIT_FAILURE. As an implementation detail, this header defines the
// new constants in terms of EXIT_SUCCESS and EXIT_FAILURE. In a new
// standard, the constants would be implementation-defined, although it
// might be worthwhile to "suggest" (which a standard is allowed to do)
// values of 0 and 1 respectively.
// Rationale for having multiple failure values: some environments may
// wish to distinguish between different classes of errors.
// Rationale for choice of values: programs often use values < 100 for
// their own error reporting. Values > 255 are sometimes reserved for
// system detected errors. 200/201 were suggested to minimize conflict.
const int exit_success = EXIT_SUCCESS; // implementation-defined value
const int exit_failure = EXIT_FAILURE; // implementation-defined value
const int exit_exception_failure = 200; // otherwise uncaught exception
const int exit_test_failure = 201; // report_error or
// report_critical_error called.
