C++ Syntax

MKI_InstanceOpen( void );

Opens a provisional instance for data block input. Once opened, the instance can be filled with data blocks and subsequently be terminated and appended to a memory list or to a block.

Only one provisional instance is available at a time. Anyway, other provisional entities like object, extended object, block and group can be open simultaneously. After opening the provisional instance, it must later be closed using MKI_InstanceClose or MKI_InstanceFastInsert.

Return Value

Address of the provisional instance, if successful. This address can be used to modify the instance's extended properties (located in ReturnValue->XProperty) and the display matrix (located in ReturnValue->DisplayMatrix). Please do not modify any other value! If nullptr is returned, this indicates that another provisional instance is already open.
