80 * The strlcat() function appends the NUL-terminated string src to the end

84 * The strlcpy() and strlcat() functions return the total length of the
85 * string they tried to create. For strlcpy() that means the length of src.
86 * For strlcat() that means the initial length of dst plus the length of
87 * src. While this may seem somewhat confusing it was done to make trunca-
88 * tion detection simple.
