Detailed Description

Mutex Lock Guard class.

The lock guard class is used to do exception-safe locking. Simply put a Lock object on the Stack. When the stack-frame is unwinded (by a throw, or a return) the Mutex will be unlocked. The following example shows how to use the Lock guard:

class X {
  void a(int val);
  private:
    Mutex mtx;
    int   var;
}

void X::a(int val)
{
  Mutex::Lock l(mtx);
  var = val;
}
