2 * sysctl.h: General linux system control interface
3 *
4 * Begun 24 March 1995, Stephen Tweedie
5 *
6 ****************************************************************
7 ****************************************************************
8 **
9 ** The values in this file are exported to user space via
10 ** the sysctl() binary interface. However this interface
11 ** is unstable and deprecated and will be removed in the future.
12 ** For a stable interface use /proc/sys.

831 *
832 * sysctl names can be mirrored automatically under /proc/sys. The

834 *
835 * The table's mode will be honoured both for sys_sysctl(2) and
836 * proc-fs access.
837 *
838 * Leaf nodes in the sysctl tree will be represented by a single file
839 * under /proc; non-leaf nodes will be represented by directories. A
840 * null procname disables /proc mirroring at this node.
841 *
842 * sysctl(2) can automatically manage read and write requests through
843 * the sysctl table. The data and maxlen fields of the ctl_table
844 * struct enable minimal validation of the values being written to be
845 * performed, and the mode field allows minimal authentication.
846 *
847 * More sophisticated management can be enabled by the provision of a
848 * strategy routine with the table entry. This will be called before
849 * any automatic read or write of the data is performed.
850 *
851 * The strategy routine may return:
852 * <0: Error occurred (error is passed to user process)
853 * 0: OK - proceed with automatic read or write.
854 * >0: OK - read or write has been done by the strategy routine, so
855 * return immediately.
856 *
857 * There must be a proc_handler routine for any terminal nodes
858 * mirrored under /proc/sys (non-terminals are handled by a built-in
859 * directory handler). Several default handlers are available to
860 * cover common cases.
