* The linux procfs state field displays one of the characters RSDZTW to
|
|
* denote running, sleeping in an interruptible wait, waiting in an
|
|
* uninterruptible disk sleep, a zombie process, process is being traced
|
|
* or stopped, or process is paging respectively.
|
|
*
|
|
* Our struct kinfo_proc contains the variable ki_stat which contains a
|
|
* value out of SIDL, SRUN, SSLEEP, SSTOP, SZOMB, SWAIT and SLOCK.
|
|
*
|
|
* This character array is used with ki_stati-1 as an index and tries to
|
|
* map our states to suitable linux states.
