* Description:
|

* Register a simple character driver at /dev/log whose write() method
|
|
* will transfer data to the SYSLOG device. This can be useful if, for
|
|
* example, you want to redirect the output of a program to the SYSLOG.
|
|
*
|
|
* NOTE that unlike other syslog output, this data is unformatted raw
|
|
* byte output with no time-stamping or any other SYSLOG features
|
|
* supported.
