Routine Description:
|
|
|
|
Exported Entry point from newdev.cpl. Installs a new device. A new Devnode is
|
|
created and the user is prompted to select the device. If the class guid
|
|
is not specified then then the user begins at class selection.
|
|
|
|
Arguments:
|
|
|
|
hwndParent - Window handle of the top-level window to use for any UI related
|
|
to installing the device.
|
|
|
|
LPGUID ClassGuid - Optional class of the new device to install.
|
|
If ClassGuid is NULL we start at detection choice page.
|
|
If ClassGuid == GUID_NULL or GUID_DEVCLASS_UNKNOWN
|
|
we start at class selection page.
|
|
|
|
pReboot - Optional address of variable to receive reboot flags (DI_NEEDRESTART,DI_NEEDREBOOT)
|
|
|
|
|
|
Return Value:
|
|
|
|
BOOL TRUE for success (does not mean device was installed or updated),
|
|
FALSE unexpected error. GetLastError returns the winerror code.
