Installs the driver, if not already installed.
|
| 26 |
Starts the driver, if not already running.
|

|
| 28 |
You can either always call "CdenableSysInstallStart" when your
|
| 29 |
program fires up and "CdenableSysStopRemove" when it terminates,
|
| 30 |
or just let the installation program call "CdenableSysInstallStart"
|
| 31 |
and leave it always be present.
|
| 32 |
|
| 33 |
I recommend the latter option. Calling "CdenableSysInstallStart"
|
| 34 |
always doesn't hurt anything, it will immediately return
|
| 35 |
with success if the service is running.
|
| 36 |
|
| 37 |
Returns non-zero if installation/startup was succesfull,
|
| 38 |
zero if anything failed.
|
| 39 |
Returns non-zero also if the driver was already running.
|
| 40 |
|
| 41 |
The file "cdenable.sys" must already have been copied to
|
| 42 |
the directory "System32\Drivers"
