.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE INTERIOR REPRESENTATION\s+2 to determine the current attribute
values for a specified entry in a specified workstation's table of
defined interior representations.
.LP
See the description of the subroutine \s-2SET INTERIOR REPRESENTATION\s+2 for information on the meaning of these attribute values.
.SS C Input Parameters
.IP \fIws\fP
Workstation identifier.
.IP \fIindex\fP
Entry to be returned from the workstation's table of interior representations;
if this entry is not present in the table and the \fItype\fP parameter is
\s-2REALIZED\s+2, the representation for interior index 1 is returned.
.IP \fItype\fP
An enumerated value specifying whether the inquired values are to be returned
as the values originally specified by the application (\s-2SET\s+2),
or as the values actually being used by the workstation
if any of the application-specified values
had to be mapped to ones available on the workstation (\s-2REALIZED\s+2).
Valid values are defined in phigs.h as:
.sp .2
.ta .5i +\w'PINQ_REALIZED     'u
.nf
	\s-2PINQ_SET\s+2	\fIReturn Application-specified Value\fP
	\s-2PINQ_REALIZED\s+2	\fIReturn Value Available on the Workstation\fP
.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 Pint_bundle structure in which the system returns the
interior representation at \fIindex\fP in the workstation's table of 
interior representations.
Pint_bundle is defined in phigs.h as follows:
.sp .4
.ta .5i +\w'Pint_style     'u +\w'colr_ind;     'u
.nf
typedef struct {
.sp .2
	Pint_style	style;	/* interior style */
	Pint	style_ind;	/* interior style index */
	Pint	colr_ind;	/* interior colour index */
.sp .2
} Pint_bundle;
.sp .2
Pint_style is defined in phigs.h as:
.sp .4
.ta .5i 
.nf
typedef enum {
.sp .2
	PSTYLE_HOLLOW,
	PSTYLE_SOLID,
	PSTYLE_PAT,
	PSTYLE_HATCH,
	PSTYLE_EMPTY,
.sp .2
} Pint_style;
.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 003
Ignoring function, function requires state 
(\s-2PHOP\s+2, \s-2WSOP\s+2, \s-2*\s+2, \s-2*\s+2)
.IP 054
Ignoring function, the specified workstation is not open
.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 100
Ignoring function, the bundle index value is less than one
.IP 101
Ignoring function, the specified representation has not been defined
