Hello friends, <br>
<br>
I am having issue with the pid_task function with arguments first as
userspace pid (using getpid fn) and 2nd argument PIDTYPE_PID.<br>
<br>
"pid_task(<pid from userspace>, PIDTYPE_PID);"<br>
<br>
Can anyone assist me what can be the cause?<br>
<br>
Have a Good Day,<br>
Thank you,<br>
Ankur.<br>
