Hi,
I wrote some code like below these days, and my colleagues and me are
not sure if the code has any concurrent problem.
Can someone help to figure out if the code has any race problem?
Thanks very much!
Code:
> package main
> import (
"sync"
"sync/atomic"
)
> func main() {
var n int32
var m sync.RWMutex
go func() {
for {
atomic.LoadInt32(&n)
}
}()
go func() {
for {
m.RLock()
atomic.AddInt32(&n, 1)
m.RUnlock()
}
}()
go func() {
for {
m.Lock()
n = 0
m.Unlock()
}
}()
// do something to keep goroutines running here
......
}
