我想在win7中使用Go將進程設(shè)置為CPU，代碼如下：package mainimport ( "fmt" "math" "runtime" "syscall" "unsafe")func SetAffinity(pid int, mask *int64) { syscall.Syscall(syscall.SYS_SCHED_SETAFFINITY, uintptr(pid), 8, uintptr(unsafe.Pointer(mask)))}func GetAffinity(pid int, mask *int64) { syscall.Syscall(syscall.SYS_SCHED_GETAFFINITY, uintptr(pid), 8, uintptr(unsafe.Pointer(mask)))}var cpuNum = float64(runtime.NumCPU())var setx = []struct { args int expected int64}{ {0, int64(math.Pow(2, cpuNum)) - 2},}func main() { for _, ca := range setx { var cpuSet int64 GetAffinity(ca.args, &cpuSet) cpuSet = cpuSet & 0XFFFFFFE SetAffinity(ca.args, &cpuSet) fmt.Println(cpuSet) GetAffinity(ca.args, &cpuSet) fmt.Println(cpuSet) }}當(dāng)我使用時go run affinity.go，獲取以下信息：# command-line-arguments.\affinity.go:12: undefined: syscall.SYS_SCHED_SETAFFINITY.\affinity.go:13: not enough arguments in call to syscall.Syscall.\affinity.go:17: undefined: syscall.SYS_SCHED_GETAFFINITY.\affinity.go:18: not enough arguments in call to syscall.Syscall我發(fā)現(xiàn)SYS_SCHED_SETAFFINITY它只在 linux 中使用。那么，我想在Windows（Win7）中使用Go將進程設(shè)置為cpu，我該怎么辦？

您必須調(diào)用 WinAPI SetProcessAffinityMask。
這樣的事情應(yīng)該工作：
func setProcessAffinityMask(h syscall.Handle, mask uintptr) (err error) {
r1, _, e1 := syscall.Syscall(syscall.NewLazyDLL("kernel32.dll").NewProc("SetProcessAffinityMask").Addr(), 2, uintptr(h), mask, 0)
if r1 == 0 {
if e1 != 0 {
err = error(e1)
} else {
err = syscall.EINVAL
}
}
return
}
h當(dāng)然，它是進程句柄，并且mask是所需的親和掩碼。
這是從BSD 許可下的Go benchmarks 中獲取的。
