Struct UnsafeAtomicCounter32
A 32-bit atomic counter.
Namespace: Unity.Collections.LowLevel.Unsafe
Syntax
public struct UnsafeAtomicCounter32Remarks
Rather than have its own int, a counter points to an int. This arrangement lets counters in different jobs share reference to the same underlying int.
