Functions ¶

func CPUTimeDiff ¶

func CPUTimeDiff(first *Rusage, latest *Rusage) (float64, float64)

CPUTimeDiff returns the differences of user CPU time and system CPU time used between two Rusage structs. It a no-op function for non-linux or appengine environment.

func GetCPUTime ¶

func GetCPUTime() int64

GetCPUTime returns the how much CPU time has passed since the start of this process. It always returns 0 under non-linux or appengine environment.

func GetTCPUserTimeout ¶

func GetTCPUserTimeout(conn net.Conn) (int, error)

GetTCPUserTimeout is a no-op function under non-linux or appengine environments a negative return value indicates the operation is not supported

func SetTCPUserTimeout ¶

func SetTCPUserTimeout(conn net.Conn, timeout time.Duration) error

SetTCPUserTimeout is a no-op function under non-linux or appengine environments

Types ¶

type Rusage ¶

type Rusage struct{}

Rusage is an empty struct under non-linux or appengine environment.

func GetRusage ¶

func GetRusage() (rusage *Rusage)

GetRusage is a no-op function under non-linux or appengine environment.
