| More specifically..
|
| bind()
| sendto()
| select() for response
|
| The select will wake on either the expiration of the timer, data to be
| read or a failure hint if it turns out nothing was listening on the port
| from the previous sendto()
Always prefer poll over select on systems that have it.
