.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE GENERALIZED STRUCTURE ELEMENT FACILITIES\s+2
to obtain a list of the \s-2GSE\s+2 identifiers supported, and whether each
is workstation-independent (i.e. supported on all workstations)
or workstation-dependent (i.e. supported on some, but not all workstations).
.SS C Input Parameters
.IP \fIlength\fP
The number of elements for which memory is allocated in the output
parameter \fIgse\fP.
0 may be specified, in order to get the \fItotal length\fP of the list.
.IP \fIstart\fP
Starting position in the list at which to begin the inquiry.
.SS C Output Parameters
.IP \fIerror_ind\fP
A pointer to the location to store the error number of any error
detected by this function.
.IP \fIgse\fP
A pointer to a Pgse_id_dep_list
in which the system returns the portion of the
\fIlist of \s-2GSE\s+2 identifiers\fP from the
\s-2PHIGS\s+2 description table, starting with \fIstart\fP.
Pgse_id_dep_list is defined in phigs.h as follows:
.nf
.ta .5i +\w'Pgse_id_dep     'u +\w'num_id_facs;     'u
.sp .4
typedef struct {
.sp .2
	Pint	num_id_facs;	/* number of identifiers/dependency element */
	Pgse_id_dep	*id_facs;	/* list of \s-2GSE\s+2 facilities */
.sp .2
} Pgse_id_dep_list;
.fi
.IP
The pointer \fIgse\fR\(->\fIid_facs\fP must be initialized to an array of
\fIlength\fP Pgse_id_dep elements, defined as:
.nf
.ta .5i +\w'Pws_dep_ind     'u +\w'ind;     'u
.sp .4
typedef struct {
.sp .2
	Pint	id;	/* GSE identifier */
	Pws_dep_ind	ind;	/* WS independent/dependent indicator */
.sp .2
} Pgse_id_dep;
.fi
.IP
Pws_dep_ind is an enumerated type, with values:
.nf
.ta .5i +\w'PWS_INDEP     'u
.sp .2
	PWS_INDEP	\fIWorkstation independent\fP
	PWS_DEP	\fIWorkstation dependent\fP
.fi
.sp .2
.IP \fItotal_length\fP
A pointer to an integer in which to return the total length of the list.
This is the value required for \fIlength\fP if all the items in the list
are to be returned.
.SH ERRORS
.IP 002
Ignoring function, function requires state 
(\s-2PHOP\s+2, \s-2*\s+2, \s-2*\s+2, \s-2*\s+2)
