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. Parameters
| lhs, rhs | - | error codes to compare |
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 Exceptions
