DESCRIPTION

Purpose

Use INQUIRE EDGE REPRESENTATION to determine the current attribute values for a specified entry in a specified workstation’s table of defined edge representations.

See the description of the subroutine SET EDGE REPRESENTATION for information on the meaning of these attribute values.

C Input Parameters

wsWorkstation identifier.

indexEntry to be returned from the workstation’s table of edge representations; if this entry is not present in the table and the type of returned value parameter is REALIZED, the representation for edge index 1 is returned.

typeAn enumerated value specifying whether the inquired values are to be returned as the values originally specified by the application (SET), 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 (REALIZED). Valid values are defined in phigs.h as:

PSET(return application-specified value)
PREALIZED(return value available on the workstation)

C Output Parameters

error_ind
A pointer to the location to store the error number of any error detected by this function.

repA pointer to a Pedgebundl structure in which the system returns the edge representation at index in the workstation’s table of edge representations. Pedgebundl is defined in phigs.h as follows:

typedef struct {
Pedgefflag;/∗ edge flag ∗/
Pinttype;/∗ edgetype ∗/
Pfloatscale;/∗ edgewidth scale factor ∗/
Pintcolour;/∗ edge colour index ∗/
} Pedgebundl;

FORTRAN Input Parameters

WKIDWorkstation identifier.

EDIEntry to be returned from the workstation’s table of edge representations; if this entry is not present in the table and the type of returned value parameter is REALIZED, the representation for edge index 1 is returned.

TYPEAn enumerated value specifying whether the inquired values are to be returned as the values originally specified by the application (SET), 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 (REALIZED). Valid values are defined in phigs77.h as:

PSET(return application-specified value)
PREALI(return value available on the workstation)

FORTRAN Output Parameters

ERRIND
The error number of any error detected by this function.

EDFLAG
The edge flag value at index EDI in the workstation’s table of edge representations.

EDTYPE
The edge type at index EDI in the workstation’s table of edge representations.

EWIDTH
The edge width scale factor at index EDI in the workstation’s table of edge representations.

COLIThe edge colour index at index EDI in the workstation’s table of edge representations.

ERRORS

003Ignoring function, function requires state (PHOP, WSOP, ∗, ∗)

054Ignoring function, the specified workstation is not open

059Ignoring function, the specified workstation does not have output capability (i.e., the workstation category is neither OUTPUT, OUTIN, nor MO)

100Ignoring function, the bundle index value is less than one

101Ignoring function, the specified representation has not been defined
