The first three arguments are lists of `waitable objects': either integers representing \UNIX{} file descriptors or objects with a parameterless method named \code{fileno()} returning such an integer. The three lists of waitable objects are for input, output and `exceptional conditions', respectively. Empty lists are -allowed. The optional last argument is a time-out specified as a +allowed. The optional \var{timeout} argument specifies a time-out as a floating point number in seconds. When the \var{timeout} argument is omitted the function blocks until at least one file descriptor is ready. A time-out value of zero specifies a poll and never blocks. |
