Hi Jovi,

interface */
static char event_handler[256];
static struct ctl_table_header *handler_header_table;
static struct ctl_table my_event_table[] = {
{
.ctl_name = KERN_EVENT_HANDLER, /* this needs to be
defined in linux/sysctl.h */
.procname = "event_handler", /*
this is the name by which the file will be created in /proc/sys/kernel */
.data = &event_handler,
/* data variable */
.maxlen = sizeof(event_handler),
.mode = 0644,
.proc_handler = &proc_dostring,
.strategy = &sysctl_string,
},
{ },
};
static struct ctl_table my_root_table[] = {
{
.ctl_name = CTL_KERN, /* create
entry in the /proc/sys/kernel */
.procname = "kernel",
.maxlen = 0,
.mode = 0555,
.child = my_event_table, /* here
we specify our child table */
},
{ },
};
static int __init my_handler_init(void)
{

handler_header_table = register_sysctl_table(my_root_table);
/* register the entry */
