// 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 | |

// report_critical_error called. | |
