| 19 | // The intent is to propose the following for addition to namespace std |
| 20 | // in the C++ Standard Library, and to then deprecate EXIT_SUCCESS and |
| 21 | // EXIT_FAILURE. As an implementation detail, this header defines the |
| 22 | // new constants in terms of EXIT_SUCCESS and EXIT_FAILURE. In a new |
| 23 | // standard, the constants would be implementation-defined, although it |
| 24 | // might be worthwhile to "suggest" (which a standard is allowed to do) |
| 25 | // values of 0 and 1 respectively. |
| 26 | |
| 27 | // Rationale for having multiple failure values: some environments may |
| 28 | // wish to distinguish between different classes of errors. |
| 29 | // Rationale for choice of values: programs often use values < 100 for |
| 30 | // their own error reporting. Values > 255 are sometimes reserved for |
| 31 | // system detected errors. 200/201 were suggested to minimize conflict. |
