+check (refer to
+.BR ptrace (2)).
+If the check denies access, then the field value is displayed as 0.

+(18) \fIpriority\fP \ %ld
+(Explanation for Linux 2.6)
+For processes running a real-time scheduling policy
+.RI ( policy
+below; see
+.BR sched_setscheduler (2)),
+this is the negated scheduling priority, minus one;
+that is, a number in the range \-2 to \-100,
+corresponding to real-time priorities 1 to 99.
+For processes running under a non-real-time scheduling policy,
+this is the raw nice value
+.RB ( setpriority (2))
+as represented in the kernel.
+The kernel stores nice values as numbers
+in the range 0 (high) to 39 (low),
+corresponding to the user-visible nice range of \-20 to 19.
+.IP
+Before Linux 2.6, this was a scaled value based on
+the scheduler weighting given to this process.
+.\" And back in Linux 1.2 days things were different again.
+.TP
+(19) \fInice\fP \ %ld
+The nice value (see
+.BR setpriority (2)),
+a value in the range 19 (low priority) to \-20 (high priority).

+.TP
+(20) \fInum_threads\fP \ %ld
+Number of threads in this process (since Linux 2.6).

+for an earlier removed field.
+.TP
+(21) \fIitrealvalue\fP \ %ld
+The time in jiffies before the next
+.B SIGALRM

+and is hard coded as 0.
+.TP
+(22) \fIstarttime\fP \ %llu
+The time the process started after system boot.
+Before Linux 2.6, this value was expressed in jiffies.

+The format for this field was %lu before Linux 2.6.
+.TP
+(23) \fIvsize\fP \ %lu
