Exported Type Names

type Value (struct) A Value provides an atomic load and store of a consistently typed value. The zero value for a Value returns nil from Load. Once Store has been called, a Value must not be copied. A Value must not be copied after first use. Load returns the value set by the most recent Store. It returns nil if there has been no call to Store for this Value. Store sets the value of the Value to x. All calls to Store for a given Value must use values of the same concrete type. Store of an inconsistent type panics, as does Store(nil).
Exported Values
func AddInt32(addr *int32, delta int32) (new int32) AddInt32 atomically adds delta to *addr and returns the new value.
func AddInt64(addr *int64, delta int64) (new int64) AddInt64 atomically adds delta to *addr and returns the new value.
func AddUint32(addr *uint32, delta uint32) (new uint32) AddUint32 atomically adds delta to *addr and returns the new value. To subtract a signed positive constant value c from x, do AddUint32(&x, ^uint32(c-1)). In particular, to decrement x, do AddUint32(&x, ^uint32(0)).
func AddUint64(addr *uint64, delta uint64) (new uint64) AddUint64 atomically adds delta to *addr and returns the new value. To subtract a signed positive constant value c from x, do AddUint64(&x, ^uint64(c-1)). In particular, to decrement x, do AddUint64(&x, ^uint64(0)).
