Hello,

Consider the following function prototype:

foo(int, ...);

Inside the body of function foo I want to call another function whose
signature is given as follows:

bar(int, ...);

No matter how many parameters are passed to foo, I want bar to be called
with the exact same parameter list. Is it possible to do this?

Thanks,

Neil

This is a comp.lang.c FAQ. Please refer to the answer to question
15.12 of the C-faq.

You may need to look at variable-argument list functions
va_arg, va_end, va_start, vsprintf etc..

passing parameter list of one function to another's a cool scene! Dig
it!

This has been answered here more than once recently. It is also in
the FAQ. The fact that you are asking this question indicates that you
have not a) read the FAQ or b) lurked in the newsgroup for any length
of time, both of which you should have done before posting. This is
very rude, not to mention a waste of bandwidth (which forces the cost
of Net access up - and I'm sick of paying for people who keep asking
the same questions all the time!). Stop doing that! Lurk for at least
a month. Read the FAQ (http://www.eskimo.com/~scs/C-faq/top.html).
Please do not post again until you have done so.
