flag: changed flag variable name in package doc, for clarity
Changed the flag variable name to nFlag instead of flagname, because flagname was confusing. Change-Id: I20dd4c4b4f605395d427a125ba4fd14580e5d766 Reviewed-on: https://go-review.googlesource.com/c/go/+/221678 Reviewed-by: Rob Pike <r@golang.org>

Define flags using flag.String(), Bool(), Int(), etc.

This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
|
||||
This declares an integer flag, -n, stored in the pointer nFlag, with type *int:
|
||||
import "flag"
|
||||
var ip = flag.Int("flagname", 1234, "help message for flagname")
|
||||
var nFlag = flag.Int("n", 1234, "help message for flag n")
|
||||
If you like, you can bind the flag to a variable using the Var() functions.
|
||||
var flagvar int
|
||||
func init() {
