Function clone_stack_with_base 

Source 
pub unsafe fn clone_stack_with_base(
    sp: *mut StackValue,
) -> (*mut StackValue, *mut StackValue)
Expand description

Clone the current stack for spawning, returning both base and sp.

This is used by spawn to create a copy of the parent’s stack for the child strand. Returns (new_sp, new_base) so the spawn mechanism can set STACK_BASE for the child.

§Safety

Current stack must have a valid base set via set_stack_base and sp must point to a valid position.
