Function CSPThreadLockHandler::Lock() Description: It increments the thread lock count by one. If the attached thread lock object is locked by another thread, this member function waits until the object is unlocked.
| Prototype: unsigned long Lock(); Arguments: No arguments (void). Return value: It returns the current thread lock count. Examples: //Global scope declarations CSPThreadLock ThreadLock; int a = 0; int b = 0; ... ... //Thread sensitive code { CSPThreadLockHandler Handler( ThreadLock ); Handler.Lock(); a += 2; b = b / a; // even on a "division by zero" exception, // the thread lock object is completely unlocked // during the destruction of object Handler. Handler.Unlock(); // even if you omit the line above, // the thread lock object will be fully unlocked // during the destruction of object Handler. } See also: member functions Unlock(), TryLock()
