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.
func CompareAndSwapInt32(addr *int32, old, new int32) (swapped bool)
CompareAndSwapInt32 executes the compare-and-swap operation for an int32 value.
func CompareAndSwapInt64(addr *int64, old, new int64) (swapped bool)
CompareAndSwapInt64 executes the compare-and-swap operation for an int64 value.
func CompareAndSwapPointer(addr *unsafe.Pointer, old, new unsafe.Pointer) (swapped bool)
CompareAndSwapPointer executes the compare-and-swap operation for a unsafe.Pointer value.
func CompareAndSwapUint32(addr *uint32, old, new uint32) (swapped bool)
CompareAndSwapUint32 executes the compare-and-swap operation for a uint32 value.
func CompareAndSwapUint64(addr *uint64, old, new uint64) (swapped bool)
CompareAndSwapUint64 executes the compare-and-swap operation for a uint64 value.
func CompareAndSwapUintptr(addr *uintptr, old, new uintptr) (swapped bool)
CompareAndSwapUintptr executes the compare-and-swap operation for a uintptr value.
func StorePointer(addr *unsafe.Pointer, val unsafe.Pointer)
StorePointer atomically stores val into *addr.
func SwapInt32(addr *int32, new int32) (old int32)
SwapInt32 atomically stores new into *addr and returns the previous *addr value.
func SwapInt64(addr *int64, new int64) (old int64)
SwapInt64 atomically stores new into *addr and returns the previous *addr value.
func SwapPointer(addr *unsafe.Pointer, new unsafe.Pointer) (old unsafe.Pointer)
SwapPointer atomically stores new into *addr and returns the previous *addr value.
func SwapUint32(addr *uint32, new uint32) (old uint32)
SwapUint32 atomically stores new into *addr and returns the previous *addr value.
func SwapUint64(addr *uint64, new uint64) (old uint64)
SwapUint64 atomically stores new into *addr and returns the previous *addr value.
func SwapUintptr(addr *uintptr, new uintptr) (old uintptr)
SwapUintptr atomically stores new into *addr and returns the previous *addr value.
