|
|
*
|
|
* Leaf nodes in the sysctl tree will be represented by a single file
|

* under /proc; non-leaf nodes will be represented by directories. A
|
|
* null procname disables /proc mirroring at this node.
|
|
*
|
|
* sysctl(2) can automatically manage read and write requests through
|
|
* the sysctl table. The data and maxlen fields of the ctl_table
|
|
* struct enable minimal validation of the values being written to be
|
|
* performed, and the mode field allows minimal authentication.
|
|
*
|
|
* There must be a proc_handler routine for any terminal nodes
|
|
* mirrored under /proc/sys (non-terminals are handled by a built-in
|
|
* directory handler). Several default handlers are available to
|
|
* cover common cases.
