R help - May 2004 - R Wrappers for "scanf-like" c functions.

I'm having difficulty trying to figure out how to write an R wrapper 
for a C                                           function that has a 
"scanf-like" argument list. Recall that in C, functions like scanf() 
return their values through a variable number of arguments whose type 
and number is determined by a format string. In C this is handled by 
parsing the format string and then applying the types and functions 
declared in <stdarg.h>.  I've been banging my head against the wall 
for a few days trying to figure out how I might do such a thing. Does 
anyone know how to write an R wrapper for functions like this?

Thanks,

-- Fernando
