Re: How to tell if thread owns critical section?

OK, I will check out you suggestions.
Where I can control things, I do keep track of Critical Sections. However,
the exceptions caught by SEH (exceptions.h) can throw on any constructor
Which is why there's this thing called a function-try-block, to handle
exceptions thrown during construction. But proper use of an RAII object
should take care of that case as well.
(for example) whether in a Critical Section or not. That, not where I
define my own exceptions, is the problem for which I was seeking an
I took the earlier advice about using my own flags and that is working

I have an app where I run a variable number of identical threads. In
to use "try-throw-catch" error handling I have "wrapped" the WorkerBee
threads in the following function:
void WorkerBeeWrapper(LPVOID lpParam)
WorkerBee( MYWORKSPACE* lpParam );
// process errors I define
catch( ... )
// process other errors
// problem is here ...
The WorkerBee() function enters and exits the same critical section as
does it's job. My problem is this: How to tell in the WorkerBeeWrapper()
function whether or not the ending thread owns the critical section.
there may be an error exit, I do not know.
If your WorkerBee function enters a critical section, it should also
leave it before it returns, no matter how it returns (reching the end of
the function, reaching a return statement, throwing an exception or
whatever. Using wrappers like CCriticalSection and CSingleLock might
help. If a function sometimes returns while still inside a critical
section and sometimes not, you should think about re-designing your code.
But don't mess around with internal data of critical sections or any
other system objects. Your program already causes enough headache, there
is no need to add another one.
