RtlGetSaclSecurityDescriptor function

Description

The RtlGetSaclSecurityDescriptor routine returns a pointer to the system ACL (SACL) for a security descriptor.

Parameters

SecurityDescriptor [in]

Pointer to the SECURITY_DESCRIPTOR whose SACL is to be returned.

SaclPresent [out]

Pointer to a Boolean variable that indicates the presence of a SACL in the specified security descriptor. If this variable receives TRUE, the security descriptor contains a SACL, and the remaining output parameters receive valid values. If this variable receives FALSE, the security descriptor does not contain a SACL, and the remaining output parameters do not receive valid values.

Sacl [out]

Pointer to a variable that receives the address of the SACL for the security descriptor. If the security descriptor does not have a SACL, this variable does not receive a value. If the security descriptor has a NULL SACL, this variable receives NULL.

SaclDefaulted [out]

Pointer to a Boolean variable that receives the value of the SE_SACL_DEFAULTED flag in the security descriptor's SECURITY_DESCRIPTOR_CONTROL structure if a SACL exists for the security descriptor.

Return value

RtlGetSaclSecurityDescriptor returns STATUS_SUCCESS or an appropriate NTSTATUS value such as the following:

Return code Description
STATUS_UNKNOWN_REVISION The security descriptor's revision level is unknown or is not supported. This is an error code.

Remarks

For more information about security and access control, see Windows security model for driver developers and the documentation on these topics in the Windows SDK.
