I'm trying launch goroutines in an infinite loop until I get the response I'm looking for but the select
is unreachable if I change for i := 0; i < 10; i++ {}
to for {}
. What's a pattern for solving this?
package main
import (
"fmt"
"math/rand"
"time"
)
func myFunc() float64 {
c := make(chan float64)
for i := 0; i < 10; i++ {
go func() {
var value float64
value = someOp()
if value > .9 {
c <- value
}
}()
}
// unreachable code the if the for loop above is infinite
for {
select {
case x := <-c:
return x
default:
}
}
}
func someOp() float64 {
rand.Seed(time.Now().UnixNano())
return rand.Float64()
}
func main() {
fmt.Println(myFunc())
}
