  * \brief Add an element into a sorted vector
  *
  * \param vec Sorted vector to add to.
- * \param elem Element to insert.
+ * \param elem Element to insert. Must not be an array type.
  * \param cmp A strcmp compatible compare function.
  *
  * \return 0 on success.
  * \return Non-zero on failure.
  *
  * \warning Use of this macro on an unsorted vector will produce unpredictable results
+ * \warning 'elem' must not be an array type so passing 'x' where 'x' is defined as
+ *          'char x[4]' will fail to compile. However casting 'x' as 'char *' does
+ *          result in a value that CAN be used.
