GPQPLR - Inquire Predefined Polyline Representation

GPQPLR (wstype, index, errind, ltype, lwidth, color)

Note:

This subroutine is a Workstation Description Table (WDT) inquiry. For an overview, see "WDT Inquiries"

Purpose

Use GPQPLR to inquire the predefined polyline attributes in an entry of the bundle table for the specified workstation type.

The graPHIGS API returns the polyline type (ltype), width (lwidth), and color (color) for the specified index of the specified workstation type.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameter. If the inquired information is unavailable, then the error indicator (errind) contains the error number indicating the reason, and the values returned in the output parameter are unpredictable.

Parameters

wstype -- specified by user, 8-byte character string

Workstation type.

index -- specified by user, fullword integer

Predefined polyline bundle table index (>=1)

errind -- returned by the graPHIGS API, fullword integer

Error indicator. If the error indicator is zero, the request has been completed. Otherwise, one of the following errors exists:

23: SPECIFIED WORKSTATION TYPE DOES NOT EXIST
35: WORKSTATION HAS ONLY INPUT CAPABILITIES
43: BUNDLE INDEX EXCEEDS WORKSTATION TABLE CAPACITY
60: BUNDLE INDEX VALUE < ONE
548: SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

ltype -- returned by the graPHIGS API, fullword integer

Line type corresponding to the specified entry in the workstation's line type table. The table size and specific entries supported are workstation dependent. The default line type table for supported entries is defined with the following line types: (1=SOLID_LINE, 2=DASHED, 3=DOTTED, 4=DASH_DOT, 5=LONG_DASH, 6=DOUBLE_DOT, 7=DASH_DOUBLE_DOT, 8-n=SOLID_LINE )

lwidth -- returned by the graPHIGS API, short floating-point number

Polyline width scale factor corresponding to the specified entry.

color -- returned by the graPHIGS API, fullword integer

Polyline color index corresponding to the specified entry.

Error Codes

None
