The answer is fairly simple. sprintf(3) is often entangled with the 
stdio library. When you use it, it depends on a bunch of other stuff
that pulls in most of stdio. Your "simple" function suddenly yanks
14K of code out of the library into your executable. Plus it is a
lot more efficient to use strxxx() routines which are simply loops
where as sprintf() invokes the _doprnt() parser to figure out how to
put together your strings. Generally, sprintf() is easier but strxxx()
routines are smaller. If your compiler/linker is smart enough to 
recognize the difference between when you want full stdio versus 
just simple printf's that helps.
