    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.
