core.atomic.cas - multiple declarations
Function cas
Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to 'ifThis'. This operation is both lock-free and atomic.

Parameters
| Name | Description |
|---|---|
| here | The address of the destination variable. |
| writeThis | The value to store. |
| ifThis | The comparison value. |
Returns
true if the store occurred, false if not.
Function cas
Stores 'writeThis' to the memory referenced by 'here' if the value
referenced by 'here' is equal to the value referenced by 'ifThis'.
The prior value referenced by 'here' is written to ifThis and
returned to the user. This operation is both lock-free and atomic.

Parameters
| Name | Description |
|---|---|
| here | The address of the destination variable. |
| writeThis | The value to store. |
