All of the atomic functions return the original value. The term "nint" can be int or uint.
nint atomicAdd(inout nint mem, nint data)
Adds data to mem.
nint atomicMin(inout nint mem, nint data)
The mem's value is no lower than data.
nint atomicMax(inout nint mem, nint data)
The mem's value is no greater than data.
nint atomicAnd (inout nint mem, nint data)
mem becomes the bitwise-and between mem and data.
nint atomicOr(inout nint mem, nint data)
mem becomes the bitwise-or between mem and data.
nint atomicXor(inout nint mem, nint data)
mem becomes the bitwise-xor between mem and data.
nint atomicExchange(inout nint mem, nint data)
Sets mem's value to data.
nint atomicCompSwap(inout nint mem, nint compare, nint data)
If the current value of mem is equal to compare, then mem is set to data.
