std.atomic
- enum msync;
- Memory synchronization flag. If the supplied option is not available on the
current platform then a stronger method will be used instead.
- hlb
- hoist-load barrier
- ddhlb
- hoist-load barrier with data-dependency "hint"
- hsb
- hoist-store barrier
- slb
- sink-load barrier
- ssb
- sink-store barrier
- acq
- hoist-load + hoist-store barrier
- rel
- sink-load + sink-store barrier
- none
- naked
- template atomicLoad(T,msync ms : cast(msync)7)
template atomicLoad(T,msync ms : cast(msync)0)
template atomicLoad(T,msync ms : cast(msync)1)
template atomicLoad(T,msync ms : cast(msync)5)
- Refreshes the contents of 'val' from main memory. This operation is both lock-free and atomic.
Returns:
The loaded value.
Params:
| val |
The value to load. This value must be properly aligned. |
- template atomicStore(T,msync ms : cast(msync)7)
template atomicStore(T,msync ms : cast(msync)4)
template atomicStore(T,msync ms : cast(msync)5)
template atomicStore(T,msync ms : cast(msync)6)
- Stores 'newval' to the memory referenced by 'val'. This operation is both lock-free and atomic.
Params:
| val |
The destination variable. |
| newval |
The value to store. |
- template atomicStoreIf(T,msync ms : cast(msync)7)
template atomicStoreIf(T,msync ms : cast(msync)4)
template atomicStoreIf(T,msync ms : cast(msync)5)
template atomicStoreIf(T,msync ms : cast(msync)6)
- Stores 'newval' to the memory referenced by 'val' if val is equal to 'equalTo'. This operation
is both lock-free and atomic.
Returns:
true if the store occurred, false if not.
Params:
| val |
The destination variable. |
| newval |
The value to store. |
| equalTo |
The comparison value. |
- struct Atomic;
- This class represents a value which will be subject to competing access. All accesses to
this value will be synchronized with main memory, and various memory barriers may be
employed for instruction ordering. Any primitive type of size equal to or smaller than
the memory bus size is allowed, so 32-bit machines may use values with size <= int.sizeof
and 64-bit machines may use values with size <= long.sizeof. The one exception to this
rule is that architectures that support DCAS will allow double-wide storeIf operations.
The 32-bit x86 architecture, for example, supports 64-bit storeIf operations.
- template load(msync ms : msync.none)
template load(msync ms : msync.hlb)
template load(msync ms : msync.ddhlb)
template load(msync ms : msync.acq)
- Refreshes the contents of this value from main memory. This operation is both lock-free and atomic.
Returns:
The loaded value.
- template store(msync ms : msync.none)
template store(msync ms : msync.ssb)
template store(msync ms : msync.acq)
template store(msync ms : msync.rel)
- Stores 'newval' to the memory referenced by this value. This operation is both lock-free and atomic.
Params:
| newval |
The value to store. |
- template storeIf(msync ms : msync.none)
template storeIf(msync ms : msync.ssb)
template storeIf(msync ms : msync.acq)
template storeIf(msync ms : msync.rel)
- Stores 'newval' to the memory referenced by this value if val is equal to 'equalTo'. This operation
is both lock-free and atomic.
Returns:
true if the store occurred, false if not.
Params:
| newval |
The value to store. |
| equalTo |
The comparison value. |
