ChangeSecurityPermissionsEx method of the Win32_PageFile class

The ChangeSecurityPermissionsExWMI class method changes the security permissions for the logical paging file that is specified in the object path (this method is an extended version of the ChangeSecurityPermissions method). If the logical file is a directory, then this method is recursive, and changes the security permissions of all of the files and subdirectories that the directory contains.

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]

Expression that resolves to an instance of Win32_SecurityDescriptor. This parameter contains new security permissions for the instance of Win32_PageFile.

Option [in]

Security privilege to be modified. For example, to change the owner and discretionary access control list (DACL) security, use the following:

Option = 1 + 4

-or-

Option = CHANGE_OWNER_SECURITY_INFORMATION | CHANGE_DACL_SECURITY_INFORMATION

Value used to set the bitMeaning
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 DACL of the logical file.

CHANGE_SACL_SECURITY_INFORMATION
8

Change the system access control (SACL) list of the logical file.

 

StopFileName [out]

Name of the file or directory where the ChangeSecurityPermissionsEx method failed. This parameter is NULL if the method succeeds.

StartFileName [in, optional]

Names the child file or directory to use as a starting point for ChangeSecurityPermissionsEx. Typically, the StartFileName parameter is the StartFileName parameter that specifies the file or directory where 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.

Recursive [in, optional]

If true, the change of ownership is applied recursively to files and directories in the directory specified by the CIM_LogicalFile instance.

Note  For file instances, the Recursive parameter is ignored.
