Functions

func Get

func Get(param string) (string, error)

Get returns kernel parameter value as a string

Example

paramValue, err := Get("kernel.random.boot_id")

if err != nil {
	panic(err.Error())
}

fmt.Printf("Boot ID: %s\n", paramValue)

func GetI

func GetI(param string) (int, error)

GetI returns kernel parameter value as an int

Example

paramValue, err := GetI("kernel.pty.max")

if err != nil {
	panic(err.Error())
}

fmt.Printf("PTY Max: %d\n", paramValue)

func GetI64

func GetI64(param string) (int64, error)

GetI64 returns kernel parameter value as an int64

Example

paramValue, err := GetI64("fs.file-max")

if err != nil {
	panic(err.Error())
}

fmt.Printf("File max: %d\n", paramValue)

Types

type Params

type Params map[string]string

Params contains all kernel parameters

func All

func All() (Params, error)

All returns all kernel parameters

Example

params, err := All()

if err != nil {
	panic(err.Error())
}

for n, v := range params {
	fmt.Printf("%s → %s\n", n, v)
}

func (Params) Get

func (p Params) Get(name string) string

Get returns kernel parameter value as a string

Example

params, err := All()

if err != nil {
	panic(err.Error())
}

fmt.Printf("Boot ID: %s\n", params.Get("kernel.random.boot_id"))

func (Params) GetI

func (p Params) GetI(param string) (int, error)

GetI returns kernel parameter value as an int

Example

params, err := All()

if err != nil {
	panic(err.Error())
}

paramValue, err := params.GetI("kernel.pty.max")

if err != nil {
	panic(err.Error())
}

fmt.Printf("PTY Max: %d\n", paramValue)

func (Params) GetI64

func (p Params) GetI64(param string) (int64, error)

GetI64 returns kernel parameter value as an int64

Example

params, err := All()

if err != nil {
	panic(err.Error())
}

paramValue, err := params.GetI64("fs.file-max")

if err != nil {
	panic(err.Error())
}

fmt.Printf("File max: %d\n", paramValue)
