CM_Reenumerate_DevNode in C#

[Hraklhs]

How can I write in C# the code at
http://support.microsoft.com/default...;EN-US;Q259697 ?
It is the following:

BOOL ScanForHardware Changes()
{
DEVINST devInst;
CONFIGRET status;

//
// Get the root devnode.
//

status = CM_Locate_DevNo de(&devInst, NULL,
CM_LOCATE_DEVNO DE_NORMAL);

if (status != CR_SUCCESS) {
printf("CM_Loca te_DevNode failed: %x\n", status);
return FALSE;

}

status = CM_Reenumerate_ DevNode(devInst , 0);

if (status != CR_SUCCESS) {
printf("CM_Reen umerate_DevNode failed: %x\n", status));
return FALSE;
}

return TRUE;
}
