VS 2010 Beta 2 doesn't support the function _set_sbh_threshold. MSDN doesn't suggest anything about deprecating this functionality.

What does "there is no long small block heap" mean?

- long block heap does not exist anymore?

- there is no longer a small block heap?

I am confused. I was using this call only to configure the debug heap to make it faster if a lot of small objects are used.

Thanks for your reply. _set_sbh_threshold is removed from VS 2010 since there is no long small block heap. We will update msdn accordingly.

Thank you for reporting your issue.
What OS do you use?
This function is only compatible for pre XP and Win2k3 Server.

It is just "Resolved as" by design. I am assuming that this function will not be supported by VS 2010.
In that case MSDN needs to be updated.
