Hi Andrew,

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.
