This method requests information about a device.

Syntax

void QueryDevice(
  UINT uCode,
  LPVOID* ppvData
);

uCode
[in] It is one of the following values.

Value	Description
QDC_SEL_DEVICE	Requests information for the selected device. In this case, *ppvData points to the DEVINFO structure containing the information for the device.
QDC_CON_DEVICE	Requests information for the connected device. In this case, ppvData points to the DEVINFO* structure containing the information for the device.
QDC_SEL_DEVICE_KEY	Gets a registry key that can be used to store selected device-specific settings. In this case, ppvData points to HKEY*. The caller must close the registry key when its usage is over.
QDC_CON_DEVICE_KEY	Gets a registry key that can be used to store connected device-specific settings. In this case, *ppvData points to HKEY. The caller must close the registry key when its usage is over.
ODC_SYNC_DATA	Gets or sets custom synchronization data from the device. ppvData is a pointer to a void pointer to SDREQUEST

ppvData
[out] A pointer to a void pointer to either a DEVINFO structure, or an HKEY (which one depends on uCode).

Returns RERR_NO_DEVICE if a selected or connected device does not exist.

If uCode specifies QDC_SYNC_DATA, the following are possible return values for this method.

Value	Description
RERR_BIG_OBJ_TYPE	The object type from the device is unknown (out of range).
RERR_BIG_CODE	The code received from the device is more than 8.
RERR_UNMATCHED	The synchronization data doesn't map to a device.
