Detailed 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.

Member Function Documentation

◆ IsLoaded()

CoreExport bool IsLoaded ( ) const

Returns true if the corresponding plug-in has been successfully loaded and initialized, false otherwise or if the plug-in has been defer-loaded.

◆ Description()

CoreExport const MCHAR* Description ( ) const

Returns the Description defined in the LibDescription function.

◆ NumberOfClasses()

CoreExport int NumberOfClasses ( ) const

Returns the number of classes implemented in the DLL.

This is the value returned by the library function LibNumberClasses.

◆ operator[]()

CoreExport ClassDesc* operator[] ( int i ) const

Returns a pointer to the 'i-th' class descriptor.

Parameters

i	- The zero based index of the ClassDesc to return.

Returns: Pointer to a class descriptor.

◆ GetClassDesc()

CoreExport ClassDesc* GetClassDesc ( int i ) const

Returns a pointer to the 'i-th' class descriptor.

This method is identical to DllDesc::operator[](int).

Parameters

i	- The zero based index of the ClassDesc to return.

Returns: Pointer to a class descriptor.

◆ operator==()

CoreExport int operator== ( const DllDesc & dd ) const

Equality operator.

Always returns zero.

◆ HasRttiSupport()

CoreExport bool HasRttiSupport ( ) const

Checks if this plugins dll was built with run-time type information (RTTI).

Precondition: NumberOfClasses must return a positive non-zero value for the check to be performed

Returns: Returns true if the dll was built with RTTI, otherwise false. In the later case, the plugin dll will not be loaded into 3ds Max and DllDesc::IsLoaded() will return false.

◆ IsBinaryCompatible()

CoreExport bool IsBinaryCompatible ( ) const

Returns true if the plug-in DLL is binary compatible with the version of 3ds Max where it's being loaded into, false otherwise.

If it return false the plugin dll will not be loaded into 3ds Max and DllDesc::IsLoaded() will return false.

CoreExport bool ImplementsCanAutoDefer ( ) const

Returns whether the corresponding plug-in DLL implements the CanAutoDefer function or not.

◆ IsPluginDllVersionValid()

static CoreExport bool IsPluginDllVersionValid ( ULONG pluginDllVersion )

static

Verifies the validity of the specified plug-in DLL version.

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.

◆ GetFullPath()

CoreExport const MSTR& GetFullPath ( ) const

Returns the full path of the plug-in DLL file this instance of DllDesc represents.

◆ GetFileName()

CoreExport const MSTR& GetFileName ( ) const

Returns the file name and extension of the plug-in DLL this instance of DllDesc represents.

◆ GetDirectoryName()

CoreExport const MSTR& GetDirectoryName ( ) const

Returns the folder name with a trailing backslash of the plug-in DLL this instance of DllDesc represents.

◆ GetHandle()

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.

◆ GetSize()

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.

◆ GetTimeLastModified()

CoreExport FILETIME GetTimeLastModified ( ) const

Returns the date and time the plug-in DLL was last modified.

◆ Unload()

void Unload ( )

◆ CallInitialize()

BOOL CallInitialize ( )

◆ CallShutdown()

BOOL CallShutdown ( )

◆ operator=()

DllDesc operator= ( const DllDesc & other )
