#3937: equal_pointees and invalid pointers
------------------------------+---------------------------------------------
Reporter: NN | Owner: no-maintainer
Type: Feature Requests | Status: new
Milestone: Boost 1.43.0 | Component: utility
Version: Boost 1.42.0 | Severity: Optimization
Keywords: |
------------------------------+---------------------------------------------
In file boost/utility/compare_pointees.hpp function equal_pointees treat
invalid pointers as a positive value.
There should be added another function which treats invalid pointers as a
negative value.
{{{
#!cpp
template<class OptionalPointee>
inline
bool equal_pointees ( OptionalPointee const& x, OptionalPointee const& y )
{
return (!x) != (!y) ? false : ( !x ? true : (*x) == (*y) ) ;
}
template<class OptionalPointee>
inline
bool equal_pointees_false ( OptionalPointee const& x, OptionalPointee
const& y )
{
return (!x) != (!y) ? false : ( !x ? false : (*x) == (*y) ) ;
}
}}}
Thanx.
