30 * According manual of strlcpy() and strlcat() the functions should return
31 * the total length of the string they tried to create. For strlcpy() that
32 * means the length of src. For strlcat() that means the initial length of
33 * dst plus the length of src. So, the function strnlen() cannot be used
34 * otherwise the return value will be wrong.
