Sorry, there was a typo. it is list_for_each_entry

If you are interested to print some fields of all task_structs. Use the following macro. It will walk thru the entire list of task_struct, starting from the current task.

struct task_struct *tskParse;
list_for_each_entry (tskParse, &(current->tasks), tasks)
{
  printk (KERN_INFO "task name = %s \n", tskParse->comm)
 
}

Hi

   I am trying to write a simple module that sort of emulates the ps command. I am trying to get the comm string for the task, using get_task_comm, but the make command keeps telling me that the symbol get_task_comm is not defined. I have included linux/sched.h. This is the header file, which I believe has the prototype definition for the function. Am I missing something?

Thanks

Hanumant
