Compares two error code objects.
1) Compares
lhs and rhs for equality.2) Compares
lhs and rhs for equality.3) Checks whether
lhs is less than rhs. Contents |
[edit] Parameters
| lhs, rhs | - | error codes to compare |
[edit] Return value
1) true if the error category and error value compare equal.
2) true if the error category or error value compare are not equal.
3) true if lhs.category() < rhs.category(). Otherwise, true if lhs.category() == rhs.category() && lhs.value() < rhs.value(). Otherwise, false
