3) Only useable on systems with /dev/null: fopen() /dev/null,
   vfprintf() to that handle and take the return value - it
   contains the number of characters written (or -1 on error).
   Then malloc() a temporary buffer to hold the complete output,
   vsprintf() to it and strncpy() to the destination array.

Of course, this might not be a suitable solution in a performance
sensitive application, but it's only a workaround for a missing
function anyway.

Ciao
