Release 10.1A: OpenEdge Development:
ADM Reference

linkRuleBuffer

Creates the dynamic table used to check the rules against a target.

Location: toolbar.p

Parameters:

pcLink AS CHAR

Name of the link.

phTarget AS Handle

Handle of any Target.

Returns: HANDLE

Notes:

The handle for the target is not created again if the link is changed. Instead, the same handle is used based on the assumption that all objects of the same type have the same API. If this is not TRUE, and the handle is not found, the data type is set to CHARACTER.
This functionality is duplicated in panel.p.
