C++ Syntax

MKI_ExtListTempOpen(

__int16 f_nPlugInNum );

Creates a provisional extended object with an empty display list. Once opened, entities can added to that provisional object's display data list using MKI_ExtTempListAddEntity. By calling MKI_ExtTempListClose, the provisional object including its complete display list will discarded.

Multiple such provisional extended objects may exist at a time.

Parameters

PlugInNum

[__int16] Internal plug-in number of the current plug-in if known. This plug-in number will be copied to the provisional extended object to accelerate internal communication between plug-in and serving application. The plug-in number can be found in any extended object's header. If unknown, use -1.

Return Value

Address of the newly created, provisional extended object, if successful. This address can be used to add entities that its display list. Returns nullptr if the creation was not successful, normally due to insufficient memory.
