strncpy() vs strncat()

Hey /prog/, I've just googled this and it returned a bunch of faggots complaining about buffer overflows.

My question is, as both functions seem to do the same thing, which one would you use?

The man page doesn't leave this clear either, it just says that strcpy zerofills the buffer.

Syntactic sugar for getters and setters? Writing them out normally is only one word and a set of parentheses longer.

Regular setters are more powerful, too, since they can have more than one argument.
