package log
Golang log.Flags function usage example
package main
import (
"fmt"
"log"
)
func main() {
fmt.Println("standard flags :", log.Flags())
// the flags constants
// see http://golang.org/pkg/log/#pkg-constants
fmt.Println("The date : ", log.Ldate)
fmt.Println("The time : ", log.Ltime)
fmt.Println("The microsecond resolution : ", log.Lmicroseconds)
fmt.Println("The full file name and line number : ", log.Llongfile)
fmt.Println("The final file name element and line number : ", log.Lshortfile)
fmt.Println("The initial values for the standard logger : ", log.LstdFlags) //LstdFlags = Ldate | Ltime
}
Output :
standard flags : 3
The date : 1
The time : 2
The microsecond resolution : 4
The full file name and line number : 8
The final file name element and line number : 16
The initial values for the standard logger : 3
