If you have a specific case that isn't covered by blocking in a go-routine, you can always use the syscall's directly, with a very similar API to what you would do in C.
For example here's the epoll ones in stdlib: https://golang.org/pkg/syscall/#EpollCreate New syscall wrappers are in the x/sys repo: https://godoc.org/golang.org/x/sys/unix On Thursday, 22 September 2011 07:04:03 UTC-7, vase wrote: > > > > 2011/9/22 André Moraes <and...@gmail.com <javascript:>> > >> In most cases you should not need to poll explicity. >> Write a goroutine that blocks while reading the contents of your fd >> (file, network, etc...), and then send the data read across a channel. >> >> Under the hood Go will take care of the poll for you. >> >> But if you really need to poll explicitly, I can't help you since I >> never had to do that. >> > > Hm...
