Using bind with assignment operator

[KD]

Hi All,

Can anyone please tell me if it is possible to bind the assignment
operator using STL or boost?

Here's some naive pseudo code which does not even compile but may help
clarify my intent:
{
bool value = true;

function f = bind(&operator=, ref(value), false);

f(); // Sets 'value' to false.
}

Thanks,
Keith

You can not obtain the address of a built-in operator.

However, it's easy to define corresponding functions, and the standard library
defines some such wrappers, although as far as I can recall not for assignment.

Since you're using Boost it may be worthwhile to check if some Boost sublibrary
defines a relevant wrapper.

If not, e.g.

template< typename T >
T& assign( T& variable, T const& value )
{
return (variable = value);
}

Here's some naive pseudo code which does not even compile but may help
clarify my intent:
{
bool value = true;

function f = bind(&operator=, ref(value), false);

f(); // Sets 'value' to false.
}

Cheers & hth.,
