package fmt
Fscanf scans text read from r(1st parameter), storing successive space-separated values into successive arguments as determined by the format. It returns the number of items successfully parsed.
Golang fmt.Fscanf() function usage examples
Example 1:
func readCon(name string) (string, error) {
var val string
in, err := os.Open(name)
if err != nil {
return "", err
}
defer in.Close()
_, err = fmt.Fscanf(in, "%s", &val) // <-- here
return val, err
}
Example 2 :
team := os.Args[0]
var answer string
fmt.Fprintf(os.Stdout, `Are you sure you want to remove team "%s"? (y/n) `, team)
fmt.Fscanf(os.Stdin, "%s", &answer) // <-- here
if answer != "y" {
fmt.Fprintln(os.Stdout, "Abort.")
return nil
}
