         content pointed by dp_fds is not modified. A return value 0 means the
         ioctl is timed out. In this case, the memory content pointed by  dp_fds
         is not modified. If the call is successful, it returns the number of
         valid pollfd entries in  the array pointed by dp_fds; the contents of
         the rest of the buffer is undefined. For each valid pollfd entry, the
!        fd field indicates the file desciptor on which the polled events
         happened. The  events field is the user specified poll events. The
         revents field contains the  events occurred. -1 is returned if the
         call fails.
