      Environment Variables
The Audit API routines use the following environment variables: 
 
| DCEAUDITOFF | If this environment variable is defined at the time the application is started, auditing is turned off. |  | DCEAUDITFILTERON | If this environment variable is defined, filtering is enabled. |  | DCEAUDITTRAILSIZE | Sets the limit of the audit trail size.  This variable overrides the limit set by the dce_aud_set_trail_size_limit( ) function. |
