以下是进程状态常量

参看进程状态

0380

0381 /* null 0 not assigned */

0382 #define SSLEEP 1 /* sleeping on high priority */

高优先级睡眠

0383 #define SWAIT 2 /* sleeping on low priority */

低优先级睡眠

0384 #define SRUN 3 /* running */

运行/就绪

0385 #define SIDL 4 /* process being created */

进程创建态，参看newproc

0386 #define SZOMB 5 /* process being terminated */

进程终结态，参看exit

0387 #define SSTOP 6 /* process being traced */

进程暂停态，参看跟踪

0388

0389 /* flag codes */

以下为进程标志

0390

0391 #define SLOAD 01 /* in core */

进程图像在内存中

0392 #define SSYS 02 /* scheduling process */

系统进程，不参与进程调度

0393 #define SLOCK 04 /* process cannot be swapped */

进程调度锁，该进程不参与进程调度

0394 #define SSWAP 010 /* process is being swapped out */

进程图像在盘交换区，一般用于子进程创建，参看进程调度

0395 #define STRC 020 /* process is being traced */

进程跟踪标志，参看跟踪

0396 #define SWTED 040 /* another tracing flag */

跟踪子进程暂停标志，参看跟踪
