NTSTATUS RtlGetSaclSecurityDescriptor( IN PSECURITY_DESCRIPTOR SecurityDescriptor, OUT PBOOLEAN SaclPresent, OUT PACL *Sacl, OUT PBOOLEAN SaclDefaulted ); Routine Description: This procedure retrieves the system ACL information of a security descriptor. Arguments: SecurityDescriptor - Supplies the security descriptor. SaclPresent - If TRUE, indicates that the security descriptor does contain a system ACL. In this case, the remaining OUT parameters will receive valid values. Otherwise, the security descriptor does not contain a system ACL and the remaining OUT parameters will not receive valid values. Sacl - This value is returned only if the value returned for the SaclPresent flag is TRUE. In this case, the Sacl parameter receives the address of the security descriptor's system ACL. If this value is returned as null, then the security descriptor has a null system ACL. SaclDefaulted - This value is returned only if the value returned for the SaclPresent flag is TRUE. In this case, the SaclDefaulted parameter receives the value of the security descriptor's SaclDefaulted control flag. Return Value: STATUS_SUCCESS - Indicates the call completed successfully. STATUS_UNKNOWN_REVISION - Indicates the revision of the security descriptor is not known to the routine. It may be a newer revision than the routine knows about.
