class TAtomicCount


TAtomicCount

Class providing atomic operations on a long. Setting, getting,
incrementing and decrementing are atomic, thread safe, operations.

TAtomicCount a(n);

(n is convertible to long)

Effects: Constructs an TAtomicCount with an initial value of n.

long(a);

Returns: (long) the current value of a.

++a;

Effects: Atomically increments the value of a.
Returns: nothing.

--a;

Effects: Atomically decrements the value of a.
Returns: (long) zero if the new value of a is zero,
unspecified non-zero value otherwise
(usually the new value).

a.Set(n);

Effects: Set a to the value n.
Returns: nothing.

a.Get();

Returns: (long) the current value of a.
