Detailed Description #

template <typename TYPE >
class Gambit::safe_variable_ptr;

A safe variable pointer that throws an informative error if you try to dereference it when nullified, but unlike safe_ptr it can be used to overwrite the thing it points to. However, it is not possible to change the address of this pointer without using the ‘set’ function (in which case you presumably know what you’re doing).
