#define ssprintf(dest, ...) snprintf((dest), sizeof(dest), __VA_ARGS__)
Could someone who understands g++ please advise how to fix this? I
don't quite understand why it doesn't work.
You need to look wherre the macro is being used, not the definition of
the macro.
It's telling you the format argument is not a string literal, and
there are no format args, suggesting it's being used something like:
ssprintf(buf, str);
That's certainly questionable code, why use snprintf() if you don't
want any printf-style formatting? strncpy would do instead, or several
other approaches.
