va_list equivalent

Hey, wondering if there is a va_list equivalent in Javascript. Well,
actually, I know that there is, but I don't know if its user...
applicable. va_list in C/++ anyhow is a way of being able to pass in
any number of arguments at the end of a function, I'll show an example:

Expand|Select|Wrap|Line Numbers

 
Header:

void addLine(int, const char*, ...);
 
cpp:

addLine(int line, const char *string, ...) {

char *output;

va_list args;

va_start(args, string);

vasprintf(&output, string, args);

va_end(args);

}

So as you can see, the space is reserved at the end of the function
declaration with the "..." syntax, and in the function body is expanded
and processed. I could be way off here, but I think I'm on the right
track. Thanks for the help.

Cheers.

I guess you are referring to the arguments object. It's a list of the
arguments passed to the function:

function blah()
{
var x;
var rpt = [];
for (var i=0, len=arguments.length; i<len; ++i){
x = typeof arguments[i];
rpt[i] = x;
if ( 'string' == x || 'number' == x ){
rpt[i] += ': ' + arguments[i];
}
}
alert('There were ' + len + ' arguments passed to the function:'
+ '\n' + rpt.join('\n')
);
}

blah('arg1',3,{});

There is no "prior" on usenet, that depends on the individual readers news-
server.

So please quote what you are replying on. [second request]

Please read the newsgroup FAQ (via sig line 3 below), particularly
Section 2.3, especially paragraphs 6 & 7 ; by understanding the medium
you have chosen to use, you will get better results.

This was highly uncalled for. I am new to this, and such an attitude
has negative helpfulness attached to it. Leave your national insults
off usenet, there is no need for that here. Can a moderator please lock
this thread? It has degenerated from its original intent, and my
question has already been answered:

Cheers.

It also has positive aspects to it. You will find reading this group's

That is certainly something that I would prefer to see less of. Any
blanket generalisation about a nation or its people is bound to be
false, and almost certainly counter-productive in an international
forum.

The comp.lang.javascript Usenet newsgroup is open, public and
unmoderated. Threads are never really closed, they just stop being
interesting after some unpredictable point. It is also worthless to
attempt to direct the discussion that follows an OP.

I can agree with that.
[color=blue]
> Can a moderator please lock this thread?[/color]

No, sorry, that's not possible. This newsgroup is not moderated. There
are no moderators.

The first sentence of Dr Stockton's post was purely informative and
good advice. The FAQ section 2.3,
<URL:http://www.jibbering.com/faq/#FAQ2_3> is recommended reading,
especially if you are new to Usenet or even just to this group.

Obviously the entire FAQ is recommended reading, that's why it's there
:)

Usenet is a discussion forum. It happens all the time that people
stray from the original subject of a thread, and there is nothing
wrong with that. If the topic changes too severely, the subject
field migh be changed, but it's not really required. The original
poster does not own the thread and cannot control what people
end up discussing (and trust me, many have tried :).

So, welcome. Hope you could use your answer.

It's true, and I did read it, I was a bit upset about his comment that
I overlooked the helpful remark. My apologies.

Understood, thanks for the information. :)

Absolutely agreed.

Agreed again.

100% correct. But after about 7 or 8 years, I have gotten so used to
JRS' pedantic crap that it doesn't bother me anymore, it just provides
me with daily humor is all.

Whether fortunate or unfortunate, this group isn't moderated and a
thread can't be "locked".

There is no "positive aspects" to John's repeated display of bigotry
towards a nation or its people and I don't think the reference to the
FAQ is what was uncalled for.

Absolutely. Thats why I post the URL every time I post here :)
