DDKWINDOWINFO (Windows Embedded CE 6.0)
1/6/2010
This structure contains address window information.
Syntax
typedef struct _DDKWINDOWINFO_tag {
DWORD cbSize;
DWORD dwBusNumber;
DWORD dwInterfaceType;
DWORD dwNumIoWindows;
DEVICEWINDOW ioWindows[MAX_DEVICE_WINDOWS];
DWORD dwNumMemWindows;
DEVICEWINDOW memWindows[MAX_DEVICE_WINDOWS];
} DDKWINDOWINFO, *PDDKWINDOWINFO;
Members
- cbSize
Size of this structure.
- dwBusNumber
PCI bus number. BusNumber in the registry, which is zero if there is no entry.
- dwInterfaceType
INTERFACE_TYPE value. Most likely, set to 5, which designates PCI. Use InterfaceTypeUndefined if there is no entry.
- dwNumIoWindows
Number of I/O windows.
- ioWindows
Array of dwNumIoWindowsDEVICEWINDOW structures, each of which describes an I/O resource window.
- dwNumMemWindows
Number of memory windows.
- memWindows
Array of dwNumMemWindows DEVICEWINDOW structures, each of which describes a memory resource window.
Remarks
The ioWindows array is populated from the IoBase and IoLen values, which can be DWORD values, in which case dwNumIoWindows is 1. If multiple I/O windows are present, IoBase and IoLen are REG_MULTI_SZ values, where each string in the multi-string is the hexadecimal value of the window base and corresponding length. The two arrays must be the same length. In this case, the ioWindows array is populated from these values and dwNumIoWindows is set to the array length. If no IoBase or IoLen value is present, dwNumIoWindows is set to zero.
