all
if the element pointed to is itself a pointer, then the target of that pointer will be taken, and so on, until an element is found which is not a pointer.
one
if the element pointed to is itself a pointer, then its target (whether a pointer or not) is taken as the target of this pointer.
none
no further evaluation of targets is carried out beyond that needed to find the element specified in the pointer's target.
解説
If no value is given, the application program is responsible for deciding (possibly on the basis of user input) how far to trace a chain of pointers.
