我想在win7中使用Go将进程设置为CPU,代码如下:
package main
import (
"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)
}
}
当我使用时go run affinity.go,获取以下信息:
# 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
我发现SYS_SCHED_SETAFFINITY它只在 linux 中使用。那么,我想在Windows(Win7)中使用Go将进程设置为cpu,我该怎么办?
