It is okay, yes.

Hey, you could factor it into strlen() + memcpy() + memset() [*], if
you don't mind walking the string twice. You could use memcpy()
instead of strncpy() in your strcpy(), too, for a minor optimisation.
It's really not worth it if you ask me; an optimised memcpy() --
and, to a lesser degree, an optimised memset() -- might be noticeable,
but for the rest of these functions?
[*] Actually, you need strnlen(), but that's not a standard function.
