|
|
TSusp (thread suspend count) output specs.
|
|
sleeping or idle threads' status (as that's presumably the signal thread).
(ps_emit_tty_name): Move guts into into ps_tty_short_name.
Tighten up types used (i.e., don't use int for everything).
|
|
one. Change MsgsIn and MsgsOut to MsgIn and MsgOut.
|
|
(ps_emit_num_blocks): Use int format for int arg.
(sprint_frac_value): Likewise.
|
|
|
|
compatible way (that is, 20 .. -20 instead of 0 .. 24). Use this instead
of ps_emit_int to print all priority fields. This also increases the min
field width for them to 3.
|
|
Use ps_user_t routines instead of querying passwd or getting the owner from
ps->info.
Increase the width of the user name field to 8.
