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.

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.
