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. | |
