Thread DataSlot

[b.fokke]

The Thread class exposes AllocateNamedDataSlot() and AllocateDataSlot()
methods which allow allocating memory for thread-specific data. How is
this different from encapsulating each running thread in a class and
using that class to store the data?

The difference is in the "thread specific data" ... By wrapping your
thread in class you do not have "thread specific data".

Bram,

The members of a class can be accessed by any thread. Encapsulating a
running thread in a class doesn't prevent other threads from accessing
the members of that class. Of course you could provide a loose
enforcement by simply making sure you don't access that class from
another thread. Contrast that with thread local storage which strictly
enforces the coupling of data to a specific thread. There may be cases
where you want multiple threads executing code in the same class, but
have their own copy of data to work with.

Thanks for both answers!
