Redim + thread

[Provoni]

Suppose the following code with multiple threads running it:

Code: Select all

sub thread(byval pointer as any ptr)
	
	dim array()
	
	do
		
		if new_data=1 then
			
			if check=1 then redim array(a,b,c)
			
			'do calculations
			
		end if
		
		'report back the main thread
		
	loop until user_terminated=1
	
end sub

Is the array placed on the stack or not? If not, is it possible to do from inside the thread?
Does the redim guarantee that any previous data in the array is cleared?

Thanks

'dim array()' defines a var-len array with:
- its descriptor on the stack,
- its elements in the heap (only a non-static and fix-len array has its elements on the stack).
The only difference from classic subs is that each thread has its own stack.

'redim' ensures that all previous data in the array is destroyed.
'redim preserve' only destroys previous data not preserved by resizing.

Thank you very much
