   int ATOMIC_INT_READ(atomic_int_t *counter);

ATOMIC_INT_READ( ) returns the integer value contained within the object referenced by counter.

counter: Points to an ATOMIC_INT(D4) object from which the integer value is to be obtained.

The integer value contained within the object referenced by counter.

The ATOMIC_INT(D4) object pointed to by counter must have been previously allocated by ATOMIC_INT_ALLOC(D3) and initialized by ATOMIC_INT_INIT(D3).

The atomicity properties of ATOMIC_INT objects are strictly limited to a single object. See ``Atomic locks'' in HDK Technical Reference.

Non-blockable, interrupt, user, or blockable context.
