NAME
       GQSGUS  (Inquire set of segment names in use) - Retrieves what segment names are currently
       in use.


SYNOPSIS
       CALL GQSGUS(N,ERRIND,OL,SGNA)


C-BINDING SYNOPSIS
       #include <ncarg/gks.h>

       void ginq_set_seg_names(Gint num_elems_appl_list, Gint start_pos, Gint *err_ind, Gint_list
       *seg_names, Gint *length_list);


DESCRIPTION
       N           (Integer, Input) - The set member requested.

       ERRIND      (Integer,  Output)  -  If  the  GKS  state  is  WSOP  (workstation open), WSAC
                   (workstation active), or SGOP (segment open), then ERRIND is returned as  "0";
                   otherwise ERRIND is returned as "7".

       OL          (Integer, Output) - The number of segment names that are currently in use.

       SGNA        (Integer,  Output)  -  If  the  GKS  state  is  WSOP  (workstation open), WSAC
                   (workstation active), or SGOP (segment open), and if OL is larger  than  zero,
                   then  SGNA  is  returned as the name in the Nth element of the list of segment
                   names that are currently in use; otherwise SGNA is undefined.


USAGE
       For NCAR GKS, segment names are integers between 0 and 99 inclusive (see the man page  for
       GCRSG).

       If  one  wants  to  obtain a list of all segment names that are currently in use, then the
       procedure usually is first to determines the number of segment names currently in  use  by
       making  an  initial  call  to GQSGUS with first argument of "1".  If ERRIND is returned as
       "0", then OL will tell you how many segments are currently in use.  Then, to get the  list
       of  all  segment  names  currently  in  use,  call  GQSGUS in a loop on N from 1 to OL and
       retrieve the N values of SGNA returned from such calls.


ACCESS
       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
