How to make the end not to the end of the line?

[Yanghui Bian]

Hello,
When in word wrapper mode, a long line is truncated by emacs. 
The function of end-of-line make the cursor go to the end of the long line 
instead of the position where
the line is truncated. 
Is there any elisp function available which have the cursor goes to the end 
where the line is truncated? 

Thanks.
