Functions ¶

func CompareKernelVersion ¶

func CompareKernelVersion(a, b VersionInfo) int

CompareKernelVersion compares two kernel.VersionInfo structs. Returns -1 if a < b, 0 if a == b, 1 it a > b

Types ¶

type Utsname ¶

type Utsname struct {
	Release [65]byte
}

Utsname represents the system name structure. It is defined here to make it portable as it is available on linux but not on windows.

type VersionInfo ¶

type VersionInfo struct {
	Kernel int    // Version of the kernel (e.g. 4.1.2-generic -> 4)
	Major  int    // Major part of the kernel version (e.g. 4.1.2-generic -> 1)
	Minor  int    // Minor part of the kernel version (e.g. 4.1.2-generic -> 2)
	Flavor string // Flavor of the kernel version (e.g. 4.1.2-generic -> generic)
}

VersionInfo holds information about the kernel.

func GetKernelVersion ¶

func GetKernelVersion() (*VersionInfo, error)

GetKernelVersion gets the current kernel version.

func ParseRelease ¶

func ParseRelease(release string) (*VersionInfo, error)

ParseRelease parses a string and creates a VersionInfo based on it.

func (*VersionInfo) String ¶

func (k *VersionInfo) String() string
