Args are ERROR-SYMBOL and associated DATA. This function does not return. +When `noninteractive' is non-nil (in particular, in batch mode), an +unhandled error calls `kill-emacs', which terminates the Emacs +session with a non-zero exit code. + An error symbol is a symbol with an `error-conditions' property that is a list of condition names. The symbol should be non-nil. A handler for any of those names will get to handle this signal. |
