Compares to another error category.
1) Checks whether *this and
rhs refer to the same object.
2) Checks whether *this and
rhs do not refer to the same object.
3) Orders *this and
rhs by the order of this and &rhs. Equivalent to std::less<const error_category*>()(this, &rhs).[edit] Parameters
| code | - | specifies the error code to compare |
| condition | - | specifies the error condition to compare |
[edit] Return value
1) true if *this and
rhs refer to the same object, false otherwise.
2) true if *this and
rhs do not refer to the same object, false otherwise.
3) true if *this is less than
