thread synchronization

Hi,

how can I synchronize 2 threads using the 'lock'-equivalent that is available in C# ?

thanks
Chris

Managed code or native?

If managed, you can use the same mechanism that C# uses: the
System.Threadin g.Monitor class - you just have to call the member functions
explicitly while the C# lock construct calls them for you.

If native, depending on what you need, you might use a CriticalSection ,
Mutex, Semphore or Event.

http://msdn.microsoft.com/library/de...on_objects.asp

is a good jumping-off point for information about the kernel synchronization
objects (Mutex, Semaphore, Event), while

http://msdn.microsoft.com/library/de...on_objects.asp

covers CriticalSection s (which are not kernel objects - they're implemented
by the win32 subsystem).

Just as an addition, here is a small code-sample (because this will be
mostly implemented without the __try-__finally):

C#:
lock(obj)
{
// Some code
}

managed C++:
System::Threadi ng::Monitor::En ter(obj);
__try
{
// Some code
}
__finally
{
System::Threadi ng::Monitor::Ex it(obj);
}
