Let's say I have two functions f1(...) and f2(...) which take a variable
argument lists.

Is there any way to have f1 call f2 function like printf() by passing part of
the variable argument list (the last part), or if not, then the whole thing?

In other words how could I call
f2(va_list ap)

instead of

f2(arg1,arg2,arg3,arg4, etc...)

I know that printf() has another function vprintf() which has that sort of
functionality, but I wonder if there is a simpler way to specify a va_list so
I don't have to have another function declaration like vprintf does for
printf.

I'm using gcc.

Please email me responses since I don't read this newsgroup often.
