Remarks The pseudo code for this is On Windows, atomic CAS is only available for 16, 32, and 64 bit integers, 64 bit is only available on 64 bit Windows. You are responsible for correctly aligning x such that the atomic increment works on the hardware you target. atomic { T val = *(&x); if (val == cmp) *(&x) = y; return val; } See Also atomicInc, atomicAdd, atomicXor, atomicDec, atomicOr SeqAn - Sequence Analysis Library - www.seqan.de
