.SH DESCRIPTION
.SS Purpose
\s-2INQUIRE TEXT REPRESENTATION PLUS\s+2 
returns the attribute values of a specified entry in a workstation
extended text bundle table.  See SET TEXT REPRESENTATION PLUS for
a full description of the contents of the bundle table entry and a
description of the extended text bundle table.
.SS C Input Parameters
.IP \fIws\fP
The workstation identifier.
.IP \fIindex\fP
The text index.
.IP \fItype\fP
An enumerated value specifying whether the values to be returned are 
those originally specified by the application (\s-2PINQ_SET\s+2), or
those resulting after \s-2PHIGS\s+2 mapped them to ones available on the
workstation (\s-2PINQ_REALIZED\s+2).  A Pinq_type structure is defined in
phigs.h as:
.nf
.ta .5i +\w'PINQ_REALIZED     'u
.sp .4
typedef enum {
.sp .2
	PINQ_SET,
	PINQ_REALIZED
.sp .2
} Pinq_type;
.fi
.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 \fIrep\fP
A pointer to a Ptext_bundle_plus structure which returns the
specified extended text representation.
Ptext_bundle_plus is defined as:
.nf
.ta .5i +1.25i  +1.25i
.sp .4
typedef struct {
.sp .2
	Pint	font;	/* text font */
	Ptext_prec	prec;	/* text precision */
	Pfloat	char_expan;	/* character expansion factor */
	Pfloat	char_space;	/* character spacing */
	Pgcolr	colr;	/* text colour */
.sp .2
} Ptext_bundle_plus;
.fi
.IP
Ptext_prec is defined as:
.sp .2
.nf
.ta .5i 
.sp .2
typedef enum {
.sp .2
	PPREC_STRING,
	PPREC_CHAR,
	PPREC_STROKE
.sp .2
} Ptext_prec;
.fi
.IP
Pgcolr is defined as:
.ta .5i +1.5i   +1i  +2i
.nf
.sp .4
typedef struct {
.sp .2
	Pint	type;	/* indirect, RGB, CIE, HSV, HLS */
	union {
	     Pint	ind;	/* index in workstation colour bundle table */
	     struct {
	          Pfloat	x;	/* red, hue, etc. */
	          Pfloat	y;	/* green, saturation, lightness, etc. */
	          Pfloat	z;	/* blue, value, saturation, etc. */
	     } general;

Constants defined for colour type are:

0	PINDIRECT	\fIIndirect\fP
1	PMODEL_RGB	\fIRed, Green, Blue\fP

3	PMODEL_HSV	\fIHue, Saturation, Value\fP
4	PMODEL_HLS	\fIHue, Lightness, Saturation\fP
.fi
.sp
The index member of the \fIval\fR union is used for 
type \s-2PINDIRECT\s+2.  The general member is used for the other types.  
.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 specified text index is not present in the text bundle table
on the workstation and the specified type of returned value is 
\fIRealized\fP,
the representation for text index one is returned.
.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 following 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 003
Ignoring function, function requires state (\s-2PHOP, WSOP, *, *\s+2)
.IP 054
Ignoring function, the specified workstation is not open
.IP 059
Ignoring function, the specified workstation does not have output
capability (that is, the workstation category is neither \s-2OUTPUT\s+2,
\s-2OUTIN\s+2, nor \s-2MO\s+2)
.IP 100
Ignoring function, the bundle index value is less than one
.IP 101
Ignoring function, the specified representation has not been defined
