I have to disagree here. Using select is REQUIRED when doing
non-blocking I/O. There is no other method for waiting until data is
available (or check which filedescriptors that have data waiting if you
are using a zero timeout).

More likely that there has been a exception of some kind. Exceptions are
not neccesary the same as errors at all times. Most people use NULL for
exception fd_set. All the normal errors are detected by read/write as
usual.
