In case I have

void foo(...) {}
void bar(...) {}

how should I call bar from foo and passing along all the parameters?

void foo(...) { bar(?); } // bar(...) doesn't work

thanks, Mikko

You have to create a different, non-variadic function that takes 
_arguments and _argptr as arguments.

See for example writefx in phobos/std/stdio.d:
    void writefx(FILE* fp,
                 TypeInfo[] arguments, void* argptr,
                 int newline=false);

Or use variadic templates, which can be passed from one function to another.

The portable version uses "std.stdarg.va_list" instead:
void writefx(FILE* fp, TypeInfo[] arguments, va_list argptr, int 
newline=false);

Should be the same for DMD, but is a built-in for GDC.
(need to use va_arg, instead of pointer manipulations)

Is there any reason why bar(...) couldn't be implemented? It's a mich 
nicer syntax.

I think we had a topic on this not much more than a week ago, and came to 
much the same conclusion.

Your link does not work.

Software error:

File-Open-Fehler (/usr/home/wikise/wiki/slurp/163.181.251.9.rl): Disc quota
exceeded at /usr/local/etc/httpd/htdocs/prowiki/wiki.cgi line 5351.

Anyway, I need to do this too, but my real question is: How do I turn off dout
buffering?  Otherwise, I need to redirect writefln(...) to fwritefln(derr,...).
