/**
 * @brief Retrieve an instance of a string for use in a program.
 *
 * @param   str The string to retrieve an instance of.
 * @param   slen The string size (<= strlen(str)).
 * @return  A pointer to an instance of the string on success.
 *          @c NULL on failure.
 *
 * This function retrieves an instance of @p str. If @p str is
 * @c NULL, then @c NULL is returned. If @p str is already stored, it
 * is just returned and its reference counter is increased. Otherwise
 * it is added to the strings to be searched and a duplicated string
 * of @p str is returned.
 *
 * This function does not check string size, but uses the
 * exact given size. This can be used to share_common part of a larger
 * buffer or substring.
