Types

type Interface

type Interface interface {
	// GetSysctl returns the value for the specified sysctl setting
	GetSysctl(sysctl string) (int, error)
	// SetSysctl modifies the specified sysctl flag to the new value
	SetSysctl(sysctl string, newVal int) error
}

An injectable interface for running sysctl commands.

func New

func New() Interface

New returns a new Interface for accessing sysctl
