Easy :) You don't need them anymore.
In stock circle it is common to use
function ()
{
char buf[some_number];
sprintf(buf...);
log(buf);
}
This avoids overwriting the global buffers which may contain something
important. With the sprintf+log function you no longer need the char buf[]
at the top of the function because you no longer to a sprintf() to a
temporary variable.
In a nutshell, delete those variables from the functions and save yourself
some memory and time allocating them. (albeit not so large)
