How do I bind an array_view to a const c-array?

Question

How do I bind an array_view to a native array that is const in the scope. See the following example:

void ThisWorks( VECTORTYPE* const_array )
{
    concurrency::array_view<

VECTORTYPE, 2> amp_output_color (width, height, const_array );
}

void ThisDoesnt( const VECTORTYPE* const_array )
{
    concurrency::array_view<VECTORTYPE, 2> amp_output_color (width, height, const_array );
}

Is there a way to make this work?

Hi Ian,

To bind a const pointer to an array_view, you would need to bind it to array_view<const T, N>.  So that the array_view only provides read access, thus respect the const-ness of the pointer. 

So what you need is:

concurrency::array_view<const VECTORTYPE, 2> amp_output_color (width, height, const_array );
