# Process notifications for Go
## Overview
The psnotify package captures process events from the kernel via
kqueue on Darwin/BSD and the netlink connector on Linux.
The psnotify API is similar to the
[fsnotify](https://github.com/howeyc/fsnotify) package.
Example:
```go
watcher, err := psnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
// Process events
go func() {
for {
select {
case ev := <-watcher.Fork:
log.Println("fork event:", ev)
case ev := <-watcher.Exec:
log.Println("exec event:", ev)
case ev := <-watcher.Exit:
log.Println("exit event:", ev)
case err := <-watcher.Error:
log.Println("error:", err)
}
}
}()
err = watcher.Watch(os.Getpid(), psnotify.PROC_EVENT_ALL)
if err != nil {
log.Fatal(err)
}
/* ... do stuff ... */
watcher.Close()
```
## Supported platforms
Currently targeting modern flavors of Darwin and Linux.
Should work on BSD, but untested.
