Pointer issue

[Brian Alvarez]

Hello Charles, im struggling because pointers do not behave the same in 32bit and 64 bit compilations,
why is that and how can i make them work the same?

For example this:

Code: [Select]

function assign(int d, byval sys * udt) as long
Invoked like this class method:

Code: [Select]

   EXAMPLE abc
   udt.assign(1, @abc)
And used like this inside udt.assign:

Code: [Select]

        ' Clear previous contents.
        copy(@udt, z, len(z))
Works in 32 bits... crashes in 64 bit mode.

Hi Brian,

When you are passing an address or anon pointer directly, the function should look like this:

Code: [Select]

function assign(int d, sys udt) as long
...
' Clear previous contents.
        copy(udt, z, len(z))


Take care. If you had covid, it can return with a harder bite.

Thanks charles, that worked pretty well!

 And yes... im taking good care of myself. In the past weeks i had fever that came and went,
headaches sore throat and other symptoms, but i never had problems breathing... it was
probably something else.

How are you?

No viral symptoms. Trying to keep as fit as possible, as I can't afford to be below par looking after my Mum. She is 94 on the 25th April.
