Purpose


GGTPK	(stat, sgna, pkid)

APL code	1399
GKS RCP code	X'38006300' (939549440)

Function: To get pick.

Input function. Returns the segment name, status and pick identifier. (See the section "GDDM-GKS restrictions" below.)

Parameters

stat (returned by GDDM) (fullword integer)
The status. The possible values are:

0 (GOK)

1 (GNPICK)

No pick

If the status equals OK, the pick input contains a segment name and pick identifier. The OK status also indicates that the pick device was pointing to an output primitive stored in a segment when the event was created. A no pick status means that the device was not pointing to a primitive inside a segment.

sgna (returned by GDDM) (fullword integer)
The segment name. This identifies the picked segment.

pkid (returned by GDDM) (fullword integer)
The pick identifier. This identifies the picked object.
