       cuted with the option.  It can be changed at any time by executing with
       the option.

       If is not specified with the option, the value of num defaults to

   Application Usage
       Use one of these:

	 ·  in program code; see sysconf(2) and the section.

	 ·  in program code; see ug_display_width(3C).

	 ·  in shell scripts; see getconf(1) and the section.

	 ·  in shell scripts

       and  all	 return	 either	 (short	 names)	 or  (long names). See ug_dis‐
       play_width(3C) for its return values.  Use one of the following	proce‐
       dures:

	 ·  In program code, call

	 ·  In a shell script,

	    1.	   Run	or  to see if long names are enabled.  If not enabled,
		   set width to

	    2.	   Else, if enabled, check for the environment	variable.   If
		   the	variable  is  set  to a value between set width to the
		   value.  Otherwise set width to

	    3.	   Else, if not set, set width to the value in the file.   Set
		   width  to  if the value is out of range, not an integer, or
		   improperly formatted.
       The current display width is used by all system and conforming applica‐
       tions  to display formatted output. See section of ug_display_width(3C)
       for usage of current display width.

EXTERNAL INFLUENCES
   Environment Variables
       If it is set and long names are enabled,
	      it overrides the width specified in the file for all system  and
	      conforming applications that write formatted output.

RETURN VALUE
       exits with one of the following values:

	      Successful completion

	      Failure

DIAGNOSTICS

	      You may have attempted to use the option for a second time.

	      You tried to use the option before using the option.

	      A call to the function failed.

WARNINGS
       The  file  is the switch that marks a long name system.	If it is miss‐
       ing, short names are assumed and the variable is ignored.

       While many programs are unaffected by long names in a short name	 envi‐
       ronment, some may behave abnormally and some may abort.

       It  is  recommended  that  you do not attempt to restore the short name
       environment once long names have been enabled.

       Do not use the system constant with the command or the function to test
       for name length; it is not changed when long names are enabled.
