How on earth do you use strconv.Atoi?

[Derrik Walker v2.0]

I really just need an example.  

I keep getting things like 

gypt.go:32: too many arguments to CALL

egypt.go:32: multiple-value strconv.Atoi64() in single-value context

egypt.go:32: x declared and not used

my code looks like:

var err os.Error

....

x := strconv.Atoi64 ( flag.Arg(0), err );

I'm sure I'm missing something obvious....

Thanks

See the documentation: http://golang.org/pkg/strconv/#tmp_58

You would want something like:

n, err := strconv.Atoi("64");
if err != nil {
// Invalid string
}

Atoi64() takes a single string as an argument, and returns multiple
values, so you want something like:

var err os.Error;
var x int64;

x, err = strconv.Atoi64(flag.Arg(0));
