List of buffer-local variables in a buffer?

List of buffer-local variables in a buffer?

[Stephen Eglen]

How do I get a list of the names of the variables that are buffer-local
within a buffer? 

(specifically, I want to protect (using the 'permanent-local
property) the many local variables that are created by term.el in M-x
term).  

Thanks, Stephen

buffer-local-variables is a built-in function in `C source code'.

(buffer-local-variables &optional BUFFER)

Return an alist of variables that are buffer-local in BUFFER.
Most elements look like (SYMBOL . VALUE), describing one variable.
For a symbol that is locally unbound, just the symbol appears in the value.
Note that storing new VALUEs in these elements doesn't change the variables.
No argument or nil as argument means use current buffer as BUFFER.
