GetEffectivePermission method of the CIM_DataFile class

The GetEffectivePermission method determines whether the caller has the aggregated permissions on the CIM_DataFile object, and the share on which the file or directory resides, as specified by the Permission argument. This method is inherited from CIM_LogicalFile.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

Syntax

boolean GetEffectivePermission(
  [in] uint32 Permissions
);

FILE_WRITE_DATA (file)FILE_ADD_FILE (directory) (2 (0x2))

Grants the right to write data to the file. For a directory, this value grants the right to create a file in the directory.

FILE_APPEND_DATA (file)FILE_ADD_SUBDIRECTORY (directory) (4 (0x4))

Grants the right to append data to the file. For a directory, this value grants the right to create a subdirectory.

FILE_READ_EA (8 (0x8))

Grants the right to read extended attributes.

FILE_WRITE_EA (16 (0x10))

Grants the right to write extended attributes.

FILE_EXECUTE (file)FILE_TRAVERSE (directory) (32 (0x20))

Grants the right to execute a file. For a directory, the directory can be traversed.

FILE_DELETE_CHILD (directory) (64 (0x40))

Grants the right to delete a directory and all the files it contains, even if the files are read-only.

FILE_READ_ATTRIBUTES (128 (0x80))

Grants the right to read file attributes.

FILE_WRITE_ATTRIBUTES (256 (0x100))
