CXlLock Class

An object which applies a lock to a CXlLockable and whose lifetime controls the duration of the lock.

class CXlLock


The CXlLock class can be used to lock an object for thread-safe access.

The most convenient way to lock a CXlLockable object is by creating a CXlLock object. CXlLock calls CXlLockable::Lock() when it is constructed, and calls CXlLockable::Unlock() when it is destroyed.

A typical usage is shown below.

CXlLockable sharedObject;
void UseSharedObject()
    CXlLock lock(sharedObject, true);
    // Do something with the sharedObject 
    // On exit from this function, the CXlLock instance will 
    // be destroyed, and sharedObject will be unlocked
