Answer Posted / sekhar
Every Process in Linux has execution priority. It ranges
from -20 (highest priority) to 19 (lowest).
Except su(Super User) others cannot increase the priority.
Only superuser can assign priority of -ve value.
Default priority is 0.
You can change your process priority using setpriority
system call.
You can get your process priority using getpriority system call.
