3) Read from a file, using select()?
4) The async I/O API.
5) Interprocess shared memory, presumably using a semaphore of some

communication.
(1) is the correct way. (5) may work if the other process and
the way you talk to it are up to the task, that is if it just
emulates (1) with the sender being another process.
(2),(3),(4) are all real-time unsafe.
