16 * Remark *
17 *****************************************************************************
18
19 1998/02/11 PH The interface to the handle manager is twofold:
20 a) HMxxx routines to be called from the "top" from the
21 KERNEL32 stubs
22 b) the HMDeviceHandler class is actually a workaround for
23 the device driver that would handle the requests on Win32.
24 To implement a new pseudo-device, one has create a new
25 HMDeviceHandler class and link it into the table in the
26 HANDLEMANAGER.CPP file.
