Multy Thread

[[Yosi]]

I have an application which run more than one thread at the sametime.
All those thread call same function (output function). How I lock this
function for other thread while one thread already use it.
in C# I done it by :
void output (String ff)
{
lock(this)
{
........
}
}

How to do that in VC++.Net ?

You need a critical section which is created with InitializeCritc alSection()
and destroyed with DeleteCritcalSe ction(). On entry to your "locked" block
you call EnterCriticalSe ction() and on exit LeaveCriticalSe ction().

Re: Multy Thread

The answer to your question heavily depends on what use and you want to do.

If you are using C++/CLI that comes with VS.NET 2005, and implement managed
code, you can include <msclr\lock.h > and use the class msclr::lock. If you
are using Managed C++, you have to call the static methode Enter/TryEnter
and Exit of System::Threadi ng::Monitor. If you are writing native code, you
have to use a Win32 API like the critical section api.
