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.
container for thread specific data storage.
ost::ThreadKey::ThreadKey | ( | ) |
Create a unique thread specific container.

Destroy a thread specific container and any contents reserved.
void* ost::ThreadKey::getKey | ( | void | ) |
Get the value of the pointer for the thread specific data container.
A unique pointer can be set for each execution context.
void ost::ThreadKey::setKey | ( | void * | ) |
Set the value of the pointer for the current thread specific execution context.
This can be used to store thread context specific data.
