.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE PREDEFINED POLYLINE REPRESENTATION\s+2 to determine
the predefined polyline representation for a specified workstation type
at a given polyline index.
.LP
.SS C Input Parameters
.IP \fItype \fP
Type of workstation.
.IP \fIindex \fP
Entry to be returned from the workstation table of predefined polyline representations.
.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 \fIbundle\fP
A pointer to a Pline_bundle data structure in which the system returns the polyline representation at \fIindex\fP in the workstation table of predefined polyline representations.  Pline_bundle is defined in phigs.h as:
.nf
.ta .5i +\w'Pfloat     'u +\w'colr_ind;     'u
.sp .4
typedef struct {
.sp .2
	Pint	type;	/* line type */
	Pfloat	width;	/* linewidth scale factor */
	Pint	colr_ind;	/* colour index */
.sp .2
} Pline_bundle; 
.fi
.IP
Values for \fItype\fR are:
.ta .5i +.5i 
.nf
	1	PLINE_SOLID
	2	PLINE_DASH
	3	PLINE_DOT
	4	PLINE_DOT_DASH
.fi
.SS Execution
.LP
If the inquired information is available, the error indicator is returned
as zero and values are returned in the output parameters.
.LP
If the inquired information is not available, the values returned in the
output parameters are undefined and the error indicator is
set to one of the below error numbers to indicate the reason for
nonavailability.
.LP
Since this is an inquiry function, \s-2ERROR HANDLING\s+2 is not invoked
when an error is detected by this function.
.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)
.IP 051
Ignoring function, this information is not yet available
for this workstation type; open a workstation of this type
and use the specific workstation type
.IP 052
Ignoring function, workstation type not recognized by the implementation
.IP 059
Ignoring function, the specified workstation does not have
output capability (in other words, the workstation category is neither 
\s-2OUTPUT\s+2, \s-2OUTIN\s+2, nor \s-2MO\s+2)
.IP 062
Ignoring function, this information is not available for this
\s-2MO\s+2 workstation type
.IP 100
Ignoring function, the bundle index value is less than one
.IP 102
Ignoring function, the specified representation has not been predefined
on this workstation
