[UFFI or CMUCL Alien] Can I use use printf-like C function from

I'd like call C function with variable number of arguments (like
printf or scanf) from Lisp (particulary, CMU CL 18e).

I guess, I can't do it with UFFI. But I can't understand from docs
how I can call it with CMU CL Alien facility.

I try to use UFFI in my project for better portability, but provide
some extensions for CMU CL (and may be SBCL) because UFFI dosn't
provide some features *yet*...

For those who is interested: I am working on PVM bindings for Common
Lisp and I am going to release it under MIT-like license. Function I
want to call is

extern int pvm_packf(const char *fmt, ...);

I see, ecl-*/contrib/pvm has bunch of code. Curprisingly, ECL is
faster than I expected.

BTW, I desided to implement pvm_packf analugue in Lisp. It just a
frontend to other PVM functions. So, I can parse format string myself
and emulate C implementation. Or use something more lispy than just
string...
