go - Wait for a non child Process to end -

hi working on simple code monitor process , restart process in case process crashes. have written small sample code.

this external process

package main  import (     "fmt"     "time" )  func main() {     {         time.sleep(1000 * time.millisecond)         fmt.println("hello")     } } 

this code monitors it.

package main  import (     "fmt"     "os" )  func main() {     p, e := os.findprocess(<processid>)     fmt.println(e)     fmt.println(p.wait())     fmt.println("done") } 

the challenge here since first process not child process of second one, not wait , directly exits. please let me know if has ideas around this.

thanks.

monitoring process exits because p.wait() not block.

from docs:

on operating systems, process must child of current process or error returned.

you can perhaps poll process pool check if process still exists.
