Device Manager Reference
The following table shows the enumerations for devices from Winbase.h.
| Enumeration | PPC | SP | Description |
|---|---|---|---|
| DeviceSearchType | X | X | This enumeration represents the ways to look for a matching device and is passed as a parameter to FindFirstDevice and FindNextDevice. |
The following table shows the functions for devices from Winbase.h.
| Function | PPC | SP | Description |
|---|---|---|---|
| ActivateDevice | X | X | This function loads a device driver. For additional functionality, use the ActivateDeviceEx function. |
| ActivateDeviceEx | X | X | This function loads a driver and adds its registry values to the Active key in the registry. |
| AdvertiseInterface | X | X | This function allows a driver to announce what interfaces it exposes. |
| DeactivateDevice | X | X | This function unloads the driver for the specified device and deletes the active key of the device from the registry. |
| DeregisterDevice | X | X | This function deregisters a registered device. DeactivateDevice supersedes this function. |
| DeviceIoControl | X | X | This function sends an IOCTL directly to a specified device driver, causing the corresponding device to perform the specified operation. |
| EnumDeviceInterfaces | X | X | This function enumerates the interfaces exposed by a driver. |
| FindFirstDevice | X | X | This function searches for device information and fills in a DEVMGR_DEVICE_INFORMATION structure with this information. |
| FindNextDevice | X | X | This function searches for devices using the handle returned from FindFirstDevice. |
| GetDeviceInformationByDeviceHandle | X | X | This function retrieves device information using a handle returned from ActivateDeviceEx. |
| GetDeviceInformationByFileHandle | X | X | This function retrieves device information using a handle returned from CreateFile. |
| RegisterDevice | X | X | This function registers a new device. ActivateDeviceEx supersedes this function. |
| ResourceCreateList | X | X | This function creates a valid set of numbers for use by drivers. |
| ResourceDestroyList | X | X | This function allows trusted code to destroy resources created with ResourceCreateList. |
| ResourceMarkAsShareable | X | X | This function allows resource ranges to be programmatically designated as shareable. |
| ResourceRelease | X | X | This function allows drivers to use operating system (OS) resources created by ResourceCreateList. |
| ResourceRequest | X | X | This function allows drivers to use the resources made available by ResourceRelease. |
| ResourceRequestEx | X | X | This function allows devices to request exclusive access to shareable resources. |
The following table shows the structures for devices from Winbase.h.
| Structure | PPC | SP | Description |
|---|---|---|---|
| DEVMGR_DEVICE_INFORMATION | X | X | This structure contains information about a device driver. Some drivers might be accessible by means of multiple names. If a particular name does not exist, the first byte of the entry in the structure is NULL. |
