INQUIRE PREDEFINED POLYLINE REPRESENTATION(3P) — Kubota Pacfic Computer Inc. (29 February 1991)

NAME

INQUIRE PREDEFINED POLYLINE REPRESENTATION − inquire a predefined polyline representation for a workstation type

SYNOPSIS

C Syntax

void
pinq_pred_line_rep ( type, index, error_ind, bundle )
Pinttype;workstation type
Pintindex;predefined index
Pint∗error_ind;OUT error indicator
Pline_bundle∗bundle;OUT predefined polyline rep

Required PHIGS Operating States

(PHOP, ∗, ∗, ∗)

DESCRIPTION

Purpose

Use INQUIRE PREDEFINED POLYLINE REPRESENTATION to determine the predefined polyline representation for a specified workstation type at a given polyline index.

C Input Parameters

type
Type of workstation.

index
Entry to be returned from the workstation table of predefined polyline representations.

C Output Parameters

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

bundleA pointer to a Pline_bundle data structure in which the system returns the polyline representation at index in the workstation table of predefined polyline representations. Pline_bundle is defined in phigs.h as:

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

Values for type are:

1PLINE_SOLID
2PLINE_DASH
3PLINE_DOT
4PLINE_DOT_DASH

Execution

If the inquired information is available, the error indicator is returned as zero and values are returned in the output parameters.

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.

Since this is an inquiry function, ERROR HANDLING is not invoked when an error is detected by this function.

ERRORS

002Ignoring function, function requires state (PHOP, ∗, ∗, ∗)

051Ignoring function, this information is not yet available for this workstation type; open a workstation of this type and use the specific workstation type

052Ignoring function, workstation type not recognized by the implementation

059Ignoring function, the specified workstation does not have output capability (in other words, the workstation category is neither OUTPUT, OUTIN, nor MO)

062Ignoring function, this information is not available for this MO workstation type

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

102Ignoring function, the specified representation has not been predefined on this workstation
