Detailed Description

The functions in this namespace are provided to assist in debugging operations performed on a worker thread.

Many operations in 3ds Max should normally always be performed in the main thread. This includes operations such as creating or deleting Animatable-derived objects and Hold system operations. In some controlled cases, these operations can be performed in worker threads, but in these cases these operations can only be performed in a single worker thread. For example, an importer may display a modal dialog with a progress bar in the main thread and perform the import in a worker thread.

Function Documentation

◆ IsInMainThread()

UtilExport bool MaxSDK::ThreadingDebuggingTools::IsInMainThread ( )

Returns true if in main thread.

◆ SetWorkerThread()

UtilExport void MaxSDK::ThreadingDebuggingTools::SetWorkerThread ( DWORD threadID = (DWORD) -1 )

Sets the worker thread id to use for testing in IsExclusivelyInMainOrWorkerThread function.

Parameters

threadID - The worker thread id. If a threadID value of -1 is used, the worker thread id is set to the current thread id

◆ GetWorkerThread()

UtilExport DWORD MaxSDK::ThreadingDebuggingTools::GetWorkerThread ( )

Returns the worker thread id set via SetWorkerThread.

If no worker thread is set, the returned value is 0.

◆ ClearWorkerThread()

UtilExport void MaxSDK::ThreadingDebuggingTools::ClearWorkerThread ( )

Clears the worker thread id value.

◆ IsExclusivelyInMainOrWorkerThread()

UtilExport bool MaxSDK::ThreadingDebuggingTools::IsExclusivelyInMainOrWorkerThread ( )

Returns true if (a) the worker thread id is not set and in main thread, or (b) the worker thread id is set and in that thread.

◆ Disable()

UtilExport void MaxSDK::ThreadingDebuggingTools::Disable ( )

Disables checking.
