+\begin{cfuncdesc}{void}{PyUnicode_InternInPlace}{PyObject **string}
+ Intern the argument \var{*string} in place. The argument must be
+ the address of a pointer variable pointing to a Python unicode string
+ object. If there is an existing interned string that is the same as
+ \var{*string}, it sets \var{*string} to it (decrementing the
+ reference count of the old string object and incrementing the
+ reference count of the interned string object), otherwise it leaves
+ \var{*string} alone and interns it (incrementing its reference
+ count). (Clarification: even though there is a lot of talk about
+ reference counts, think of this function as reference-count-neutral;
+ you own the object after the call if and only if you owned it before
+ the call.)
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{PyObject*}{PyUnicode_InternFromString}{const char *v}
+ A combination of \cfunction{PyUnicode_FromString()} and
+ \cfunction{PyUnicode_InternInPlace()}, returning either a new unicode
+ string object that has been interned, or a new (``owned'') reference to
+ an earlier interned string object with the same value.
