Tips for Debugging Threads in Native Code
Here are some tips you can use when debugging threads in native code:
You can view the contents of the Thread Information Block by typing @TIB in the Watch window or QuickWatch dialog box.
You can view the last error code for the current thread by entering @Err in the Watch window or QuickWatch dialog box.
C Run-Time Libraries (CRT) functions can be useful for debugging a multithreaded application. For more information, see _malloc_dbg.
