问题描述
是否已启用WINAPI 64位SetThreadAffinityMask()?哪些Windows操作系统(WS2K3 32位，WS2K3 64位，WS2K8 32位，WS2K8 64位等)支持使用它来将亲和力分配给64个逻辑CPU?谢谢.
Is the WINAPI SetThreadAffinityMask() 64-bit enabled? Which Windows operating systems (WS2K3 32-bit, WS2K3 64-bit, WS2K8 32-bit, WS2K8 64-bit, other) support using it to assign affinity to 64 logical CPU's? Thanks.
推荐答案
是的，SetThreadAffinityMask支持64位掩码，因为mask参数是DWORD_PTR而不是DWORD(为x64编译时也是64位)和针对x86编译时为32位).
Yes, SetThreadAffinityMask supports a 64-bit mask, as the mask parameter is a DWORD_PTR rather than a DWORD (so is 64-bits when compiled for x64 and 32-bits when compiled for x86).
