DESCRIPTION

Purpose

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

See the description of the subroutine SET POLYLINE 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 polyline representations; if this entry is not present in the table and the type of returned value parameter is REALIZED, the representation for polyline 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 Plnbundl structure in which the system returns the polyline representation at index in the workstation’s table of polyline representations. Plnbundl is defined in phigs.h as follows:

typedef struct {
Pinttype;/∗ line type ∗/
Pfloatwidth;/∗ linewidth scale factor ∗/
Pintcolour;/∗ colour index ∗/
} Plnbundl;

FORTRAN Input Parameters

WKIDWorkstation identifier.

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

LTYPE
The line type at index PLI in the workstation’s table of polyline representations.

LWIDTH
The line width scale factor at index PLI in the workstation’s table of polyline representations.

COLIThe colour index at index PLI in the workstation’s table of polyline 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
