That would likely collide with another field of the same name which is the operation's results. If it really is errno, the name is fine. It's generic enough that it can be reused on other events if that mattered. > From the audit field dictionary (link given below) "result" is already > a known field that is used to indicate the result of the audited operation. > > @Steve\Paul: > Like "res" is "result" also expected to have only values "0" or "1", or > can it be any result code? It should only be 0 or 1. Sometime in the past it may have been the words success/fail. But we've been converting those as we find them. -Steve > https://github.com/linux-audit/audit-documentation/blob/master/specs/fields > /field-dictionary.csv > > res alphanumeric result of the audited operation(success/fail) > > result alphanumeric result of the audited operation(success/fail)
