IEEE 1394 Unit Filter Driver Functions (Windows CE 5.0)
The following table shows the IEEE 1394 unit filter driver functions with a description of the purpose of each.
| Programming element | Description |
|---|---|
| UNIT_AllocateLocalPlugCB | This function must be provided by the subunit driver. |
| UNIT_FreeLocalPlugCB | This function, provided by a subunit driver, is called by the unit filter driver when an outside node has requested that a subunit disconnect itself and free a local serial bus plug. |
| UNIT_ConnectToRemotePlugCB | This function is called when a request has arrived for your subunit to initiate a connection to a serial bus plug on a particular node. |
| UNIT_DisconnectFromRemotePlugCB | This function is called by the unit filter driver when a request has arrived requesting that your subunit disconnect from a particular remote plug, which is one previously connected through UNIT_ConnectToRemotePlugCB. |
| UNIT_OpenUnitDeviceObject | This function permits a subunit driver to open the appropriate unit filter driver. |
| UNIT_CloseUnitDeviceObject | The function permits a subunit driver to close and free references to the unit driver obtained in a previous call to UNIT_OpenUnitDeviceObject. |
