// 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. |
|
