Class Lwt_engine . poll_based

inherit t

method private virtual poll : (Unix.file_descr * bool * bool) list ->
  float ->
  (Unix.file_descr * bool * bool) list

poll fds tiomeout, where fds is a list of tuples of the form (fd, check_readable, check_writable), waits for either:

one of the file descriptor with check_readable set to true to become readable
one of the file descriptor with check_writable set to true to become writable
timeout to expire

and returns the list of file descriptors with their readable and writable status.
