[omniORB] pthreads for solaris, linux ... mach?

[ERIKSSON,TOBIAS (A-Sweden,ex1)]

Thanx Gary,
 Although, there is something strange, if I put a try{ }catch(...){}
around my delete of the mutex, it does not pick up the exception.
e.g.

try
{
	if( myMutex )
	{
		delete myMutex;
		myMutex=NULL;
	}
}
catch(...)
{
	cerr << "Woops! and exception." << endl;
}

I never get this far, the application ends with stacktrace below anyway.
How can this be?

Regards
 Tobias

   If you look at the source for posix.cc again, you'll see that
THROW_ERRORS() is a macro which checks the return value of its
argument and throws an exception if it returned an error.
