hex.pointers.set_flip_pointer

Sets both to_flip and to_flip_var to point to the given pointer.
(  to_flip{_var} = ptr  )
ptr is a hex[:w/4] that holds an address.

Signature

def set_flip_pointer ptr < .to_flip, .to_flip_var { ... }

Defined in hex/pointers/basic_pointers.fj — lines 64–67 (view on GitHub).

Complexity

• Time: w(0.5@+2)

• Space: w(0.5@+14)
