argc() not work in vimrc

[aj3423]

Describe the bug In vimrc, argc() always returns 0, even when launched with argument like nvim-gtk some_file, it should return 1. I also tried put the argc() in au VimEnter:

function! s:test()
    let n = argc()
    echom n
endfunction
au VimEnter * call s:test()

But still no luck.

After the gui launched, I type command :echo argc(), it shows "1", but why it's not working in vimrc?
