WordPress MU

Is there a function that returns the current blog ID number? that is, the blog prefix number?

$blog_id

It's not a function but a variable passed through the code.

I tried that. I think it's too early in the stream because I get

Undefined variable: blog_id

I'm putting the call in the main index.php page prior to the main wp-blog-header.php include. Maybe that's the problem.

Is there a way to call the variable prior to this include?

You're not forgetting the dollar sign, are you?

I can't do a search through the code on this computer. It's going to have to be tomorrow before I check this out.

What are you trying to do anyway?

Gotta call it as a global, first.

I was looking at the globals but I would thik it would be where you called it from.

Seems that I get an error if I try to use $blog_id with out
global $blog_id;
first.

function fubar() {
global $blog_id;

echo $blog_id;
}

That the very basics of it, but you get the idea.
Gotta make it available to the function if it needs it.
No different than wpdb, or others.
