Here is the complete list of the error symbols in standard Emacs,
grouped by concept. The list includes each symbol's message (on the
error-message
property of the symbol) and a cross reference to a
description of how the error can occur.
Each error symbol has an error-conditions
property that is a
list of symbols. Normally this list includes the error symbol itself
and the symbol error
. Occasionally it includes additional
symbols, which are intermediate classifications, narrower than
error
but broader than a single error symbol. For example, all
the errors in accessing files have the condition file-error
. If
we do not say here that a certain error symbol has additional error
conditions, that means it has none.
As a special exception, the error symbol quit
does not have the
condition error
, because quitting is not considered an error.
See section 10.5.3 Errors, for an explanation of how errors are generated and handled.
