DllDesc Class Reference

#include <plugin.h>

Class Description

This class models a plug-in DLL.

3ds Max creates an instance of this class for each plugin dlls that it loads. This class allows for querying a number of plug-in DLL properties and the plug-in classes that expose.

Plugins must be built with support for RTTI, and must export all of the following functions in order for them to be loaded into 3ds Max.

• ULONG LibVersion(void) - See LibVersionProcPtr for details
• const MCHAR* LibDescription(void) - See LibDescriptionProcPtr
• int LibNumberClasses(void) - See LibNumberClassesProcPtr
• ClassDesc* LibClassDesc(int i) - See LibClassDescProcPtr

Plugins may implement the following functions for added flexibility:

• int LibInitialize(void) - See LibInitializeProcPtr
• int LibShutdown(void) - See LibShutdownProcPtr
• ULONG CanAutoDefer(void) - See CanAutoDeferProcPtr

Class DllDir represents the plug-in Dll "registry" and offers various way to get to DllDesc instances.

The supplied version number is valid if it identifies a 3ds Max SDK version that is binary compatible with the one used to compile the instance of 3ds Max that is being asked to validate this version number.

Parameters

pluginDllVersion

The plug-in DLL version to validate. This is a value returned by the plug-in DLL's LibVersion() function.

Returns

True if the supplied plug-in DLL version number corresponds to a plug-in DLL that is binary compatible with the instance of 3ds Max that is currently used.

CoreExport const HINSTANCE GetHandle

(

)

const

Returns the module handle of the plug-in DLL represented by this DllDesc instance.

The module handle should not be used to load or unload the plug-in DLL.

CoreExport DWORD GetSize

(

)

const

Returns the size of the linear space that the plug-in DLL occupies in memory, in bytes, or 0 if the plug-in DLL is not loaded.
