Varargs in C#

[jgh07]

I found the following in this document:

Varargs refers to passing or receiving a variable number of arguments for a call.

C# varargs, using the params keyword, are at the IL level just normal calls with a fixed number of parameters.

Managed varargs (using C#'s pseudo-documented "...", __arglist, etc.) are implemented almost exactly like C++ varargs. [...]

What is meant by 'pseudo-documented "..."'? I know what __arglist is and I thought it was the only way to declare varargs methods in C#, but according to this document, it also supports the C syntax? I tried the following, but it does not compile.

void Test(...) {}

Is this an error in the documentation or does this syntax actually exist?

No, this syntax doesn't exist. The paragraph you mentioned is speaking figuratively, you can read 'pseudo-documented "..."' as 'pseudo-documented "bananas"', followed by the statement that __arglist is C#'s "bananas".

That's what I thought, but the comma and 'etc.' threw me off, suggesting there is more than just __arglist.
