| // 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. |
