 If \var{*buffer} points to a non-\NULL{} pointer (an already allocated
-buffer), \cfuntion{PyArg_ParseTuple()} will use this location as
+buffer), \cfunction{PyArg_ParseTuple()} will use this location as
 buffer and interpret \var{*buffer_length} as buffer size. It will then
 copy the encoded data into the buffer and 0-terminate it. Buffer
 overflow is signalled with an exception.
