Functions

func BytePtrToString

func BytePtrToString(p *uint8) string

borrowed from net/interface_windows.go

func ByteToString

func ByteToString(orig []byte) string

func CreateQuery

func CreateQuery() (syscall.Handle, error)

CreateQuery XXX copied from https://github.com/mackerelio/mackerel-agent/

func GetWmic

func GetWmic(target string, query ...string) ([][]string, error)

exec wmic and return lines splited by newline

func IntToString

func IntToString(orig []int8) string

func PathExists

func PathExists(filename string) bool

func ReadLines

func ReadLines(filename string) ([]string, error)

ReadLines reads contents from file and splits them by new line. A convenience wrapper to ReadLinesOffsetN(filename, 0, -1).

func ReadLinesOffsetN

func ReadLinesOffsetN(filename string, offset uint, n int) ([]string, error)

ReadLines reads contents from file and splits them by new line. The offset tells at which line number to start. The count determines the number of lines to read (starting from offset):

n >= 0: at most n lines
n < 0: whole file

func StringContains

func StringContains(target []string, src string) bool

Check the target string slice containes src or not

Types

type CounterInfo

type CounterInfo struct {
	PostName    string
	CounterName string
	Counter     syscall.Handle
}

CounterInfo copied from https://github.com/mackerelio/mackerel-agent/

func CreateCounter

func CreateCounter(query syscall.Handle, pname, cname string) (*CounterInfo, error)

CreateCounter XXX

type FILETIME

type FILETIME struct {
	DwLowDateTime  uint32
	DwHighDateTime uint32
}

type PDH_FMT_COUNTERVALUE_DOUBLE

type PDH_FMT_COUNTERVALUE_DOUBLE struct {
	CStatus     uint32
	DoubleValue float64
}

type PDH_FMT_COUNTERVALUE_LARGE

type PDH_FMT_COUNTERVALUE_LARGE struct {
	CStatus    uint32
	LargeValue int64

type PDH_FMT_COUNTERVALUE_LONG

type PDH_FMT_COUNTERVALUE_LONG struct {
	CStatus   uint32
	LongValue int32
	// contains filtered or unexported fields
}
