var l sync.Mutex
var a string
func f() {
a = "hello, world"
l.Unlock()
}
func main() {
l.Lock()
go f()
l.Lock()
print(a)
}
I'm a new gopher, reading a blog about lock and having a problem, in
general , we use sync.Mutex in pairs, in the above code why could it call
lock two times in main.
Any help is Appreciated.
Thanks in advanced.
