Functions

func DesktopDir

func DesktopDir() (string, error)

func ForbiddenCentOs5x

func ForbiddenCentOs5x() error

Golang does not support CentOS 5.x

func GetAllUsedPercent

func GetAllUsedPercent(duration time.Duration) ([]float64, error)

获取所有CPU的使用百分比，以数组返回

func GetAppBinFolder

func GetAppBinFolder(name string) string

func GetAppLogFolder

func GetAppLogFolder(name string) string

Windows: Linux: MacOS: ~/Library/items/<App>

func GetCombinedUsedPercent

func GetCombinedUsedPercent(duration time.Duration) (float64, error)

获取所有CPU的使用百分比，组合成总百分比后返回

func GetCpuCount

func GetCpuCount() int

func GetEnv

func GetTimeWaitReuse

func GetTimeWaitReuse() bool

func SetEnv

func SetEnv(key, value string) error

func SetSocketLimit

func SetSocketLimit(size uint32)

func SetSystemLang

func SetSystemLang()

func SetSystemProxy

func SetSystemProxy(defaultServer string, enabled bool) error

func SetTimeWaitRecycle

func SetTimeWaitRecycle(onoff bool)

echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle

func SetTimeWaitReuse

func SetTimeWaitReuse(onoff bool)

echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse

func SysRootDir
