Fair enough. However, i don't think my misunderstanding is related to
arguments of that function.

True. 

My problem is that I have some string, _which is not displayed anywhere_
yet. I need to obtain its real width along with the width of a single
character in order to compute the length argument in `make-string'.

I may be missing something obvious.

`string-width' applies to a string. `window-text-pixel-size' doesn't.
This is the root of my misunderstanding, I guess.

Regards,
