I've unsuccessfully tried to find a method to examine the Thread Environment Block (AKA Thread Information Block) when debugging native code with the Visual Studio 2010.

I know that FS:[0] should point at it, but the value in FS seems ambiguous.

Just use the pseudo variable, @tib. You can put it in a watch expression or, more likely to be useful, put it in the Address box of a Debug + Windows + Memory window.

Also notable is the Windbg !teb command. If gives you a formatted view of the TEB content.

  • Now that you've pointed at pseudo variables , I've looked for a complete reference and [found](http://msdn.microsoft.com/en-us/library/ms164891%28VS.100%29.aspx) that 'TIB' is documented ( It does however , works as I've checked ) – Edgar James luffternstat Nov 27 '13 at 18:45
  • Surely you meant it is *not* documented? It is not afaik. – Hans Passant Nov 27 '13 at 18:53
  • Of course (I've accidentally pre-post but Its seems to be too late to edit now) . It was actually supposed to be a request for a reference to all other undocumented pseudo variables , if such exist. – Edgar James luffternstat Nov 27 '13 at 18:59
