SetPrivateObjectSecurity info Overview Group

The SetPrivateObjectSecurity function modifies a private object’s security descriptor.

BOOL SetPrivateObjectSecurity(

SECURITY_INFORMATION SecurityInformation,	// type of security information
PSECURITY_DESCRIPTOR ModificationDescriptor,	// address of SD to apply to object
PSECURITY_DESCRIPTOR *ObjectsSecurityDescriptor,	// address of object’s SD
PGENERIC_MAPPING GenericMapping,	// address of access-mapping structure
HANDLE Token	// handle of client access token
);

Parameters

SecurityInformation: Specifies a SECURITY_INFORMATION structure identifying the contents of the security descriptor pointed to by the ModificationDescriptor parameter.
ModificationDescriptor: Points to a SECURITY_DESCRIPTOR structure to be applied to the object.
ObjectsSecurityDescriptor: Points to a pointer to a SECURITY_DESCRIPTOR structure to be altered by this function. This security descriptor must be in self-relative form.
GenericMapping: Points to a GENERIC_MAPPING structure specifying the mapping of generic to specific and standard access types for the object.
Token: Identifies the access token for the client on whose behalf the private object’s security is being modified. This parameter is required to ensure that the client has provided a legitimate value for a new owner security identifier (SID). The token must be open for TOKEN_QUERY access.

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

The object’s security descriptor must be in self-relative form.

If necessary, the SetPrivateObjectSecurity function allocates additional memory to produce a larger security descriptor.

The SetPrivateObjectSecurity function is successful only if the following conditions are met:

If the object’s owner is being set, the calling process must have either WRITE_OWNER permission or be the object’s owner.
If the object’s discretionary access-control list (ACL) is being set, the calling process must have either WRITE_DAC permission or be the object’s owner.
If the object’s system ACL is being set, the SE_SECURITY_NAME privilege must be enabled for the calling process.

The process calling this function must not be impersonating a client.
