ChangeSecurityPermissionsEx method of the CIM_DataFile class
The ChangeSecurityPermissionsEx method changes the security permissions for the logical data file specified in the object path (this method is an extended version of the ChangeSecurityPermissions method). If the logical file is actually a directory, then this method will act recursively, changing the security permissions for all of the files and sub-directories that the directory contains.
Important
The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.
Syntax
uint32 ChangeSecurityPermissionsEx(
[in] Win32_SecurityDescriptor SecurityDescriptor,
[in] uint32 Option,
[out] string StopFileName,
[in, optional] string StartFileName,
[in, optional] boolean Recursive
);
Parameters
-
SecurityDescriptor [in]
-
Specifies security information.
Note
A NULL ACL in the SECURITY_DESCRIPTOR structure grants unlimited access. For more information about the implications of unlimited access, see Creating a Security Descriptor for a New Object.
-
Option [in]
-
Security privilege to modify. For example, to change the owner and DACL security, use:
Option = 1 + 4orOption = CHANGE_OWNER_SECURITY_INFORMATION | CHANGE_DACL_SECURITY_INFORMATION -
CHANGE_OWNER_SECURITY_INFORMATION (1)
-
Change the owner of the logical file.
-
CHANGE_GROUP_SECURITY_INFORMATION (2)
-
Change the group of the logical file.
-
CHANGE_DACL_SECURITY_INFORMATION (4)
-
Change the ACL of the logical file.
-
CHANGE_SACL_SECURITY_INFORMATION (8)
-
Change the system ACL of the logical file.
StopFileName [out]
String that represents the name of the file (or directory) where the method failed. This parameter is null if the method succeeds.
StartFileName [in, optional]
String that represents the child file (or directory) to use as a starting point for this method. Typically, the StartFileName parameter is the StopFileName parameter specifying the file or directory at which an error occurred from the previous method call. If this parameter is null, the operation is performed on the file (or directory) specified in the ExecMethod call.
If StartFileName is used, Recursive must be set to true as well.
Recursive [in, optional]
If True, the method is also applied recursively to files and directories within the directory that is specified by the CIM_DataFile instance. For file instances, this parameter is ignored.
Return value
Returns a value of 0 (zero) on success, and any other number to indicate an error. For additional error codes, see WMI Error Constants or WbemErrorEnum. For general HRESULT values, see System Error Codes.
