It seems they do:
RETURN VALUES
The strlcpy() and strlcat() functions return the total length of the
string they tried to create. For strlcpy() that means the length of s=
rc.
For strlcat() that means the initial length of dst plus the length of
src. While this may seem somewhat confusing, it was done to make trun=
ca=E2=80=90
tion detection simple.
