acet-error-restore

(acet-error-restore)

Resets the error handler to original error handler which was active at preceding call of (acet-error-init) and also restores saved system variables (if any were stored).

Note :
(acet-error-init) and (acet-error-restore) functions can be used in nested function calls.
In such case, the UNDO operation handling is initialised resp. executed only in the first, outermost calls to (acet-error-init) and (acet-error-restore),
while system variables are properly saved and restored with each nesting level.
