C++ Syntax

void

MKI_UndoFinishProcess(

__int32 f_nCommand,

const LPCWSTR f_pszInfo,

__int32 f_nCode );

Validates a previously started undo level. All objects, instances and blocks created since the last MKI_UndoInitProcess call now valid, objects deleted since then are permanently deleted.

Parameters

f_nCommandID New in Version 2024.2

[__int32] identifies the plug-in command that is responsible for the changes. The value of f_nCommandID is either zero (if the plug-in has only one command without a submenu) or a value between one and the number of commands listed in the f_pCommandData array of the plug-in's MKI_PLUGIN_ID structure. If the plug-in is either an import or export filter, f_nCommandID should always be zero.

f_pszInfo New in Version 2024.2

[const LPCWSTR] Address of a text that describes the command that caused the process (e.g. "Draw > Line > Point - Point"). This text will be displayed in the change history. Only the first 63 characters will be used. Set to nullptr if no description is available.

f_nCode New in Version 2022.1

[__int32] Code for the type of change that was performed on the drawing, see MKI_CHANGECODE_*. This type will be used to summarize all changes made to a drawing when asking whether to save it.
