C-h f get-buffer
(get-buffer "*Mutt*")
The Elisp manual is your friend. In the manual, `i buffer RET' takes you to the
Buffers chapter. Buffer Names in the menu there shows you this:
Function: get-buffer buffer-or-name
This function returns the buffer specified by BUFFER-OR-NAME. If
BUFFER-OR-NAME is a string and there is no buffer with that name,
the value is `nil'. If BUFFER-OR-NAME is a buffer, it is returned
as given; that is not very useful, so the argument is usually a
name. For example:
(setq b (get-buffer "lewis"))
=> #<buffer lewis>
(get-buffer b)
=> #<buffer lewis>
(get-buffer "Frazzle-nots")
=> nil
See also the function `get-buffer-create' in *note Creating
Buffers::.
