Class-Qualified Device Names

  • Article

Beginning with Windows CE .NET version 4.10, power-manageable devices can belong to varying device classes. These device classes consist both of predefined classes as well as custom device classes. The Power Manager APIs that accept device names can also accept class-qualified device names. For example, each of the following names is a valid device name:

  • COM1:
  • {A32942B7-920C-486b-B0E6-92A702A99B35}\COM1:
  • {98C5250D-C29A-4985-AE5F-AFE5367E5006}\CISCO1
  • {8DD679CE-8AB4-43c8-A14A-EA4963FAA715}\DSK1:

If a class does not qualify a device name, the device is assumed to belong to the default device class. For example, the names COM1: and {A32942B7-920C-486b-B0E6-92A702A99B35}\COM1: are equivalent.
