Parameters

hKey  SafeRegistryHandle

A handle to an open registry key.

This handle is returned by the RegCreateKeyEx or RegOpenKeyEx(SafeRegistryHandle, String, UInt32, Int32, IntPtr) function.

watchSubtree  Boolean

If this parameter is , the function reports changes in the specified key and its subkeys.

If the parameter is , the function reports changes only in the specified key.

notifyFilter  RegNotifyChangeFilter

A value that indicates the changes that should be reported.

hEvent  IntPtr

A handle to an event.

If the asynchronous parameter is , the function returns immediately and changes are reported by signaling this event.

If asynchronous is , hEvent is ignored.

asynchronous  Boolean

If this parameter is , the function returns immediately and reports changes by signaling the specified event.

If this parameter is , the function does not return until a change has occurred.

If hEvent does not specify a valid event, the asynchronous parameter cannot be .

Return Value

If the function fails, the return value is other Win32ErrorCode error code.
