Macro SYSTEM_ERROR2_CONSTEXPR14

#define SYSTEM_ERROR2_CONSTEXPR14

Defined to be constexpr when on C++ 14 or better compilers. Usually automatic, can be overriden.

Macro SYSTEM_ERROR2_TRIVIAL_ABI

#define SYSTEM_ERROR2_TRIVIAL_ABI

Defined to be [[clang::trivial_abi]] when on a new enough clang compiler. Usually automatic, can be overriden.

Macro SYSTEM_ERROR2_NAMESPACE

#define SYSTEM_ERROR2_NAMESPACE

The system_error2 namespace name.

Macro SYSTEM_ERROR2_NAMESPACE_BEGIN

#define SYSTEM_ERROR2_NAMESPACE_BEGIN

Begins the system_error2 namespace.

Macro SYSTEM_ERROR2_NAMESPACE_END

#define SYSTEM_ERROR2_NAMESPACE_END

Ends the system_error2 namespace.

Struct system_error2::traits::is_move_bitcopying

template <class T>
struct is_move_bitcopying
{
    static constexpr bool const value;
};

Specialise to true if you guarantee that a type is move bitcopying (i.e.

its move constructor equals copying bits from old to new, old is left in a default constructed state, and calling the destructor on a default constructed instance is trivial). All trivially copyable types are move bitcopying by definition, and that is the unspecialised implementation.

Macro SYSTEM_ERROR2_FATAL

#define SYSTEM_ERROR2_FATAL(msg)

Prints msg to stderr, and calls std::terminate(). Can be overriden via predefinition.
