Can you give a C code example?

... the "(where possilbe)" is a very "flexible" restriction (wide
interpretation field...) ... printf / sprintf really is a wellknown
and infamous drawback of C, e. g. new versions of Visual C compiler
use many "bizarre tricky techniques" to reveal possible printf errors
(but mostly such errors arrive of course because of the possibility to
mix pointers and numbers in the "flexible argument list" - this anyway
clearly is impossible in Lua).
