ChangeSecurityPermissionsEx method of the Win32_CodecFile class

The ChangeSecurityPermissionsEx WMI class method changes the security permissions for the codec file 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 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 descriptor contains new security permissions for the instance of Win32_CodecFile.

Option [in]

Actual 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

CHANGE_OWNER_SECURITY_INFORMATION (1 (0x1))

Change the owner of the logical file.

CHANGE_GROUP_SECURITY_INFORMATION (2 (0x2))

Change the group of the logical file.

CHANGE_DACL_SECURITY_INFORMATION (4 (0x4))

Change the discretionary access control list (DACL) of the logical file.

CHANGE_SACL_SECURITY_INFORMATION (8 (0x8))

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

StopFileName [out]

Name of the file or directory where the ChangeSecurityPermissionsEx method failed. This parameter is null when 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 StopFileName 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 changes of ownership are applied recursively to files and directories in the directory that the CIM_LogicalFile instance specifies. For file instances, the Recursive input parameter is ignored.

Return value

Returns an value of 0 (zero) if the permissions are changed, and a different number to indicate an error.
