Since, current is an inline function returning struct task_struct *,
it should work fine.
For your error message it seems that sched.h and/or asm/current.h is
not included?
Did you include <asm/current.h> and <sched.h>? :)
You are right i included <linux/sched.h> but not <asm/current.h> :(
Now it compiles all right. But there is still few doubts.
Why didn't the same code compile with including just <linux/sched.h>
and not <asm.current.h> when i use code like this ->
#include <linux/module.h>
#include <linux/init.h>
#include <linux/sched.h>
MODULE_LICENSE("GPL");
static int __init init(void)
{
struct task_struct *p;
p = current;
printk(KERN_DEBUG "%u", p->pid); <- gives error on this line.
return 0;
}
static void __exit exit(void)
{
printk(KERN_DEBUG "\nCurrent process is now in exit as %u", current->pid);
}
module_init(init);
module_exit(exit);
on the other hand if i use printk(KERN_DEBUG "%u", current->pid); in
the offending line i can compile it wihtout any hiccups, why?
Second doubt dmesg shows me pid of the current process during insmod
as 2445. but when i rmmod the module it has changed to 2445<7> why?
why is it not showing the KERN_DEBUG priority before also.On the
second thoughts why is <7> there at all?
Any links or pointers?
Thank you
Pradeep
