I wrote implementations of strlcat and strlcpy for systems that don't have
them some time back, along with fairly complete test suites, and released
them into the public domain. You're quite welcome to use them. (They're
trivial functions, but that saves someone else the effort of writing them
and testing them.)
Likewise, there's a public domain version of snprintf that I've been using
for some time for systems that either don't have snprintf (rare these
days) or that have a buggy / pre-C99 version (all versions of Solaris
prior to 9).
