Detailed Description

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.

Member Function Documentation

void* 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.

Returns

a unique void * for each execution context.

void 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.

Parameters

-	ptr to thread context specific data.
