Struct UnsafeAtomicCounter64
A 64-bit atomic counter.
Namespace: Unity.Collections.LowLevel.Unsafe
Syntax
public struct UnsafeAtomicCounter64Remarks
Rather than have its own long, a counter points to a long. This arrangement lets counters in different jobs share reference to the same underlying long.

UnsafeAtomicCounter64(Void*)
Initializes and returns an instance of UnsafeAtomicCounter64.
Declaration
public UnsafeAtomicCounter64(void *ptr)Parameters
| Type | Name | Description |

Counter
The long that is modified by this counter.
Declaration
public long *CounterField Value
| Type | Description |
|---|---|
| Int64* | The long that is modified by this counter. |
Methods
Add(Int64)
Atomically adds a value to this counter.
