For my cross-platform application I have started to use Boost, but I can't understand how I can implement code to reproduce behavior of Win32's critical section or .Net's lock
.
I want to write a method Foo
that can be called from different threads to control write operations to shared fields. Recursive calls within the same thread should be allowed (Foo() -> Foo()).
In C# this implementation is very simple:
object _synch = new object();
void Foo()
{
lock (_synch) // one thread can't be lock by him self, but another threads must wait untill
{
// do some works
if (...)
{
Foo();
}
}
}
With boost you can use boost::lock_guard<> class:
class test
{
public:
void testMethod()
{
// this section is not locked
{
boost::lock_guard<boost::recursive_mutex> lock(m_guard);
// this section is locked
}
// this section is not locked
}
private:
boost::recursive_mutex m_guard;
};
PS These classes located in Boost.Thread library.
