Determining thread count

Friends,

How to know, no of threads that are executing currently

Currently I am taking one global variable and incrementing and decrementing the variable using following methods in determining the thread count

::InterlockedIncrement(&threadCounter);
::InterlockedDecrement(&threadCounter);

Rather using above idea, I want the idea similar to this where I can know direct thread count

thanks

>> As far as I know, you can't get a direct count of threads for current process in C++

See the above code.

BTW, a more complicated solution would be to 'CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, GetCurrentProcessId());' and counting the threads, but...

>>See the above code.
This is not a direct thread count, just a trick similar to author proposal.
Your second alternative has the same flavour.

Java language, which I don't like to use by the way, mantains an internal ready-made thread list and counter.
Also you can have a similar counter with .net environment with System.Threading.ThreadPool class (have a look to ).
But I have not seen a "GetThreadCount" function in WinAPI.

I tend to object. You might want to explain why this does not work rather than only claiming that.
Just in case I haven't been clear, I was speaking of an implicitly loaded DLL. And I am really courious about the reason why a 'snapshot' should be a 'trick'.
