APL code	1478
GKS RCP code	X'3800B400' (939570176)

Function: To inquire fill area representation.

Inquiry function. Returns the representation associated with a given fill area index at a workstation, from the workstation state list.

Parameters

wkid (specified by user) (fullword integer)
The workstation identifier.

fai (specified by user) (fullword integer)
The fill area index.

type (specified by user) (fullword integer)
The type of returned values. The possible values are:

0 (GSET)

Set

1 (GREALI)

Realized

If type equals set, the values are the same as those originally passed by the Set fill area representation (GSFAR) function call. If type equals realized, the returned values are the closest available actual values at that device.

errind (returned by GDDM) (fullword integer)
The error indicator.

ints (returned by GDDM) (fullword integer)
The fill area interior style. The possible values are:

0 (GHOLLO): Hollow
1 (GSOLID): Solid
2 (GPATTR): Patterned
3 (GHATCH): Hatched

styli (returned by GDDM) (fullword integer)
The fill area interior style index. This gives the hatch style or pattern according to ints.

coli (returned by GDDM) (fullword integer)
The fill area color index.

Operating states

GKOP, WSOP, WSAC, SGOP
