bool operator==( const error_category& rhs ) const; | (1) | (since C++11) |

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).Parameters
| code | - | specifies the error code to compare |
| condition | - | specifies the error condition to compare |
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 rhs as defined by the order of this and &rhs.Exceptions
