Pathname identifying location of buffer .
An external format spec.
A buffer whose contents are examined.
Length (an integer) up to which buffer should be examined.
The result of reading the value returned from the
encoding
or
external-format
option as a Lisp expression in the
keyword
package.
Looks in the file options (EMACS-style
-*-
line) for an option called
encoding
or
external-format
, with value
value
.
If found, it reads
value
as a Lisp expression in the
keyword
package and merges
ef-spec
with
value
and returns the result as
result
. Thus it does not override a supplied
ef-spec
.
