- Description
The TDx_Draw::GetDeviceIdentifier method provides information uniquely identifying the device driver.
The information this method retrieves can be used to identify specific hardware so that problems relating to that particular hardware may be dealt with.
If the method call fails, the OnError event will be triggered with the following value:
DDERR_INVALIDPARAMS
- Parameters
DeviceIdentifier
The DeviceIdentifier parameter references a TDDDeviceIdentifier component for holding the driver details if this method returns successfully.
Flags
The Flags parameter defines a flag indicating which information is to be retrieved.
The described effect applies when the flag is set.
-
DDGDI_GETHOSTIDENTIFIER
Retrieve information about the host, often 2-D, hardware rather than the stacked secondary 3-D adapter.
A stacked secondary 3-D adapter may appear to be part of the host adapter, but often it may be located on a separate card.
When this flag is not set information regarding the secondary adapter will be retrieved.
