Ah, ok, sorry.
I think the following could be a base for automatic sanitizing of sprintf
<bash>
# converts sprintf commands into sprintf functions
sed $1 -e 's/sprintf \([A-Za-z_0-9]*\) \(.*\)/string \1 = sprintf(\2)/'
</bash>
better (preserves indentation and adds a comment)
<sprintf.sed>
s/^\([ \t]*\)sprintf \([A-Za-z_0-9]*\) \(.*\)/\1# was: sprintf \2 \3\n\1string \2 =
sprintf(\3)\n/
</sprintf.sed>
<bash>
sed $1 -f sprintf.sed
</bash>
so for example
<hansl>
sprintf ii "%d", i-2
</hansl>
becomes
<hansl>
# was: sprintf ii "%d", i-2
string ii = sprintf("%d", i-2)
</nansl>
