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. (*T) Load() (x interface{}) (*T) Store(x interface{})
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)).
func AddUintptr(addr *uintptr, delta uintptr) (new uintptr) AddUintptr atomically adds delta to *addr and returns the new value.
