.TH "INQUIRE EDGE REPRESENTATION" 3P "29 February 1991"
.SH NAME
INQUIRE EDGE REPRESENTATION \- inquire an edge representation on a workstation
.IX "Attribute Representations" "INQUIRE EDGE REPRESENTATION"
.SH SYNOPSIS
.SS C Syntax
.ft B
.ta 1.25i 3i
.nf
void
pinq_edge_rep ( ws, index, type, error_ind, rep )
Pint ws; \fIworkstation identifier\fP
Pint index; \fIedge index\fP
Pinq_type type; \fItype of returned value\fP
Pint *error_ind; \fI\s-2OUT\s+2 error indicator\fP
Pedge_bundle *rep; \fI\s-2OUT\s+2 edge representation\fP
.fi
.ft R
.SS Required PHIGS Operating States
(PHOP, WSOP, *, *)
.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE EDGE REPRESENTATION\s+2 to determine the current attribute
values for a specified entry in a specified workstation's table of
defined edge representations.
.LP
See the description of the subroutine \s-2SET EDGE 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 edge representations;
if this entry is not present in the table and the
\fItype of returned value\fP parameter is \s-2REALIZED\s+2,
the representation for edge 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 .3i +1.25i
.nf
PINQ_SET \fIReturn Application-specified Value\fP
PINQ_REALIZED \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 Pedge_bundle structure in which the system returns the
edge representation at \fIindex\fP in the workstation's table of
edge representations.
Pedge_bundle is defined in phigs.h as follows:
.sp .4
.ta .5i +1i +1i
.nf
typedef struct {
.sp .2
Pedge_flag flag; /* edge flag */
Pint type; /* edgetype */
Pfloat width; /* edgewidth scale factor */
Pint colr_ind; /* edge colour index */
.sp .2
} Pedge_bundle;
.sp .2
.fi
Valid values for the Pedge_flag enumerated type are defined in phigs.h as:
.sp .2
.ta .5i
.nf
PEDGE_OFF
PEDGE_ON
.sp .2
.fi
.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
