9 Here is the complete list of the error symbols in standard Emacs,
10 grouped by concept. The list includes each symbol's message (on the
11 @code{error-message} property of the symbol) and a cross reference to a
12 description of how the error can occur.
14 Each error symbol has an @code{error-conditions} property that is a
15 list of symbols. Normally this list includes the error symbol itself
16 and the symbol @code{error}. Occasionally it includes additional
17 symbols, which are intermediate classifications, narrower than
18 @code{error} but broader than a single error symbol. For example, all
19 the errors in accessing files have the condition @code{file-error}.
21 As a special exception, the error symbol @code{quit} does not have the
22 condition @code{error}, because quitting is not considered an error.
