A printf wrapper

Dear skilled cadencers,

I'd like to write a wrapper for the printf() function. The problem is
that I do not know how to have a variable number argument. I tried
with @[EMAIL PROTECTED]
( myPrint(****t str @[EMAIL PROTECTED]
 args)
    fprintf(****t str args)
    newline(****t)
)

however this won't work because args is a list and fprintf (or printf)
complains about that.
How can I achieve this task?

Thanks,
mb
