Hi all,
I read that in order to get the current time by using
do_gettimeofday( struct timeval *tv) function we need
to disable the inturrepts because we can't access both
fields of timeval struct tv_sec and tv_usec. Why is it
so ? also i read code from Linux device drivers book
that
they are reading all the values in /proc interface. is
it compulsary to do so ?
This is my code ....
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/time.h>
#include <asm-i386/system.h>
int init_module(void)
{
struct timeval tv;
unsigned long flags;
save_flags( flags );
cli();
do_gettimeofday(&tv);
printk("\n\t The current time is %f",( time_t
)tv.tv_sec);
restore_flags( flags );
sti();
return 0;
}
void cleanup_module(void)
{
}
Plz guide me where i am going wrong.
Thanks in advance,
Deepak Joshi.
