PollFDEvent
Description:
public enum PollFDEvent
A bitmask of events that Cogl may need to wake on for a file descriptor.
Note that these all have the same values as the corresponding defines for the poll function call on Unix so they may be directly passed
to poll.
Content:

- IN - there is data to read
- PRI - data can be written (without blocking)
- OUT - there is urgent data to read.
- ERR - error condition
- HUP - hung up (the connection has been broken,
usually for pipes and sockets).
