view-buffer

view-buffer is an interactive autoloaded compiled Lisp function in `view.el'.


(view-buffer BUFFER &optional EXIT-ACTION)

View BUFFER in View mode, returning to previous buffer when done.
Emacs commands editing the buffer contents are not available; instead, a
special set of commands (mostly letters and punctuation) are defined for
moving around in the buffer.
Space scrolls forward, Delete scrolls backward.
For a list of all View commands, type H or h while viewing.

This command runs the normal hook `view-mode-hook'.

Optional argument EXIT-ACTION is either nil or a function with buffer as
argument. This function is called when finished viewing buffer. Use
this argument instead of explicitly setting `view-exit-action'.

Do not set EXIT-ACTION to `kill-buffer' when BUFFER visits a
file: Users may suspend viewing in order to modify the buffer.
Exiting View mode will then discard the user's edits. Setting
EXIT-ACTION to `kill-buffer-if-not-modified' avoids this.

This function does not enable View mode if the buffer's major-mode
has a `special' mode-class, because such modes usually have their
own View-like bindings.
