Notes:

The SetupDiEnumDeviceInfo function retrieves a context structure for a device information element of the specified device information set. Each call returns information about one device. The function can be called repeatedly to get information about several devices.

Parameters

DeviceInfoSet

in Handle to the device information set containing the devices for which to return element information.

MemberIndex

in Zero-based index to the list of interfaces in the device information set. You should first call this function with the MemberIndex parameter set to zero to obtain the first interface. Then, repeatedly increment MemberIndex and retrieve an interface until this function fails and GetLastError returns ERROR_NO_MORE_ITEMS.

DeviceInfoData

out Pointer to an SP_DEVINFO_DATA structure that receives information about this element. You must set the cbSize member to sizeof(SP_DEVINFO_DATA) before calling this function.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
