Would it not be simpler to use variadic arguments, since that
doesn't require the programmer to set up several arrays of structures - or
do you think that the potential for a very long parameter list is
a significant disadvantage ? Eg the prototype:
int newsyslog(char *required_field1, char *required_field2, ...); /* [1] */
and then use:
newsyslog("foo", "bar", "optional_field1", "baz", "optional_field2", "bang", N
ULL);
I have used something like this for my logging+refmon infrastructure [2], in
the hope of making it as easy as possible for the programmer to report things.

[1] ignoring your length specifiers, though there shouldn't be any
reason why they couldn't be included.
