select() is probably your only option. Using signals is indeed a bad idea,
because you can't control the exact point at which your read() gets interrupted
by the timeout.

I don't think so. select() doesn't actually read data.

select() is available on most modern UNIX systems. However,
you may find slight differences in implementation, especially in error
conditions. Read the man pages carefully.
