In that commit referenced below, a new field was added
to the ps program which required adding 2 newlib items
together. Such a need is now satisfied by the library.
So, this commit will just adapt ps for that provision.

* table 3 maps macro to specifiers
|

* table 5 maps datatype to justification,width,widewidth,sorting,printing
|
|
*
|
|
* Here, "datatype" could be user,uid,u16,pages,deltaT,signals,tty,longtty...
|
|
* It must be enough to determine printing and sorting.

* After the tables, increase width as needed to fit the header.

// "PRI" is created by "opri", or by "pri" when -c is used.
|
|
//
|
|
// Unix98 only specifies that a high "PRI" is low priority.
|
|
// Sun and SCO add the -c behavior. Sun defines "pri" and "opri".
|
|
// Linux may use "priority" for historical purposes.
|
|
//
|
|
// According to the kernel's fs/proc/array.c and kernel/sched.c source,
|
|
// the kernel reports it in /proc via this:
|
|
// p->prio - MAX_RT_PRIO
|
|
// such that "RT tasks are offset by -200. Normal tasks are centered
|
|
// around 0, value goes from -16 to +15" but who knows if that is
|
|
// before or after the conversion...
|
|
//
|
|
// <linux/sched.h> says:
|
|
// MAX_RT_PRIO is currently 100. (so we see 0 in /proc)
|
|
// RT tasks have a p->prio of 0 to 99. (so we see -100 to -1)
|
|
// non-RT tasks are from 100 to 139. (so we see 0 to 39)
|
|
// Lower values have higher priority, as in the UNIX standard.
|
|
//
|
|
// In any case, pp->priority+100 should get us back to what the kernel
|
|
// has for p->prio.
|
|
//
|
|
// Test results with the "yes" program on a 2.6.x kernel:
|
|
//
|
|
// # ps -C19,_20 -o pri,opri,intpri,priority,ni,pcpu,pid,comm
|
|
// PRI PRI PRI PRI NI %CPU PID COMMAND
|

|
|
// 34 65 65 5 -20 94.7 8687 _20
|
|
//
|
|
// Grrr. So the UNIX standard "PRI" must NOT be from "pri".
|
|
// Either of the others will do. We use "opri" for this.
|
|
// (and use "pri" when the "-c" option is used)
