The Linux kernel maintains a global
variable called jiffies, which represents the number of timer ticks since
the machine started. This variable is initialized to zero and increments each timer
interrupt.
The jiffies global and
associated functions are
provided in ./linux/include/linux/jiffies.h.
asmlinkage long sys_getjiffies( void )
{
return (long)get_jiffies_64();
}
do
you know your jiffer ?
