| 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.
