.SH DESCRIPTION
.SS Purpose
\s-2INQUIRE PREDEFINED POLYMARKER REPRESENTATION PLUS\s+2
returns the
attribute values of a specified predefined entry in the
extended polymarker bundle table of a workstation type's workstation
description table.
See 
\s-2SET POLYMARKER REPRESENTATION PLUS\s+2
for a full description of
the contents of the bundle table entry
and a description of the extended polymarker bundle table.
.LP
This is a \s-2PHIGS\s0 Extension function based on
\s-2PHIGS PLUS\s+2 and is not part of the \s-2PHIGS\s+2 standard.
.SS C Input Parameters
.\" All of the following data types are predefined in phigs.h.
.IP \fItype\fP
The workstation type.
.IP \fIindex\fP
The index of the predefined entry to be returned.
.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 Pmarker_bundle_plus structure that returns the
requested representation.
Pmarker_bundle_plus is defined in phigs.h as:
.nf
.ta .5i +\w'Pgcolr     'u +\w'colr;     'u
.sp .4
typedef struct {
.sp .2
	Pint	type;	/* marker type */
	Pfloat	size;	/* marker size scale factor */
	Pgcolr	colr;	/* marker colour */
.sp .2
} Pmarker_bundle_plus;
.fi
.IP
See \s-2SET POLYMARKER REPRESENTATION PLUS\s+2
for a full description of the contents of this structure.
.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)
.IP 051
Ignoring function, this information unavailable for this 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
(i.e., 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
