I am trying to create a map of addresses of objects that I create with the time at which it is allocated. The key is the address returned by the call to new()
. How do I get the address returned by new()
?
type T struct{a, b int }
func main(){
var t int64 = time.Nanoseconds()
memmap := make(map[uint8]int64)
fmt.Printf("%d
", t)
var ptr *T = new(T)
ptr.a = 1
ptr.b = 2
fmt.Printf("%d %d %p %T
", ptr.a, ptr.b, ptr, ptr)
//memmap[ptr] = t //gives error
//var temp uint8 = ptr//gives error
}
Please tell me what should be the type of the key field in the map so that I can store the address returned by new()
? I plan to use new()
with different types, get the allocated address and map it with the creation time.
