move-end-of-line vs just search for newline char?

move-end-of-line vs just search for newline char?

[Xah Lee]

There's the move-end-of-line function. The source code and doc seems a
bit complicated.

my question is, what's the difference if i just call

  (search-forward "\n")
  (backward-char 1)

Thanks.

I think (end-of-line 1) is the preferred way of going to the end of line.

move-end-of-line is an interactive command and it has to take care of various stuff.   Your alternative might not work in a CRLF line-ending format or if there is no newline at the end of the buffer.

Thanks. good answer.

this shouldn't matter though because in buffer, newline char is always
represented by "\n". End of buffer problem is a good one still, i
think.

They'll do different things if point is already at the end of a line.
They'll do different things if a line of text wraps onto two lines on the
screen.
