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 src.
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 trunca‐
tion detection simple.
