C++ Syntax

MKI_RefOpen( void );

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

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

Return Value

Address of the provisional drawing reference, if successful. This address can be used to modify the drawing reference'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 drawing reference is already open.
