This class allows the creation of a thread context unique "pointer" that can be set and retrieved and can be used to create thread specific data areas for implementing "thread safe" library routines.
Finally, Common C++ supports a thread-safe "AtomicCounter" class. This can often be used for reference counting without having to protect the counter with a separate Mutex counter. This lends to lighter-weight code.
ThreadKey ()
| ThreadKey |
Create a unique thread specific container.
~ThreadKey ()
| ~ThreadKey |
[virtual]
Destroy a thread specific container and any contents reserved.
void * getKey (void)
| getKey |
Get the value of the pointer for the thread specific data container. A unique pointer can be set for each execution context.
Returns: a unique void * for each execution context.
void setKey (void *)
| setKey |
Set the value of the pointer for the current thread specific execution context. This can be used to store thread context specific data.
Parameters:
ptr | to thread context specific data. |
