Have I got byte alignment right?

[JPulham]

I have been playing around with byte alignment in irrArray. I've added to the class.

Code: Select all

T *array_ptr;
unsigned short byte_align;

and added this to the begining of the 'reallocate' method and replaced all 'delete [] data's with 'delete [] array_ptr'

Code: Select all

        if(byte_align)
        {
            new_size += byte_align;
            array_ptr = new char[new_size];
            data = (unsigned long*)(((unsigned long)array_ptr + byte_align) & (0xffffffff - (byte_align - 1)));
        }
        else
        {
            data = array_ptr = new T[new_size];
        }

does this look right or am I setting myself up for a massive bug?
