/***************************************************************************
* Command: ps
*
* Displays all sorts of useful information about a process.
*
* SGI changes:
* 1) Removed all the security junk.
* 2) Removed DIRSIZ and replaced it with MAXNAMLEN
* 3) Put in the notinteresting() routine to cut search time
* 4) Removed remote file system support (MAYBE)
* 5) Ignore syscon and systty entirely, they are always links
* to some other device
* 6) Redid all output with format strings
*
***************************************************************************/
/* Overall scheme:
main() Process the args setting appropriate flags and saving
away pids etc for later matching.
Build the line out format fEntry[].
Loop over entries in /proc using PIOCPSINFO.
Select the interesting procs and pass them to prcom().
FillFormat() Builds a string of field names based on the flags.
FormatSpecifier()
Takes either the FillFormat() string or the -o string
and creates the fEntry data.
prcom() Prints out info{} formatted according to fEntry[].
info{} Saves the current process entry's state.
fEntry[] Describes the line format as formatted fields.
