You guys are all crazy. I would just write an snappendf() function,
similar to snprintf(), and use a static buffer.
snappendf(buf, bufsize, ctl, ...);
Have the function return the index of where the \0 would normally go
had the buffer been big enough. So the last snappendf():
r = snappendf(...)
if (r >= bufsize)
... data was truncated ...
The routine is about 5 lines of code.
